00:03:10

Let's get acquainted

00:03:12

I I have experience working in universities, I

00:03:17

am a teacher for our specialists,

00:03:19

I also have

00:03:21

industrial experience as a

00:03:23

design engineer, I also worked as a

00:03:25

designer at an oil

00:03:27

refinery.

00:03:30

So, one more thing. I would like to

00:03:34

tell you that the

00:03:36

main course is technical maintenance,

00:03:39

current repairs of tanks and

00:03:41

tank farms, which will take place with

00:03:44

us on 12 14 September

00:03:48

there will be a 25 percent discount on it until September 4,

00:03:56

here the 25 percent discount is valid until September 4,

00:04:05

that is, until September 4 you

00:04:09

have a discount on tariffs,

00:04:12

so the following

00:04:16

means until September 4 there is a discount on the

00:04:21

professional retraining tariff,

00:04:23

more details about the full course on the

00:04:27

broadcast button or according to the PR code, these are the main

00:04:33

organizational issues,

00:04:36

these questions will be answered in more detail by

00:04:39

the Moderators. So, Our course,

00:04:44

the purpose and types of tanks It would be

00:04:49

very cool, Guys, if you,

00:04:54

as they say,

00:04:56

wrote down some points on which

00:04:58

I will dwell. So, the purpose and

00:05:02

types of tanks

00:05:04

One of the most important elements of

00:05:07

the functioning of industrial

00:05:08

production are reservoirs, the

00:05:11

purpose of the reservoirs is to

00:05:14

receive storage and delivery of various

00:05:17

liquids such as water, oil, oils,

00:05:22

dew gum, and so on, and gaseous

00:05:26

media, oil,

00:05:30

oil and liquid petroleum products

00:05:34

are stored in reservoirs specially

00:05:36

constructed by him, the capacity of

00:05:39

which ranges from 50 to

00:05:42

10 thousand cubic meters What can we

00:05:47

say about oil oil This is one of the

00:05:51

main resources of our planet that

00:05:56

are used in almost every field,

00:05:59

it is an integral part of the

00:06:03

modern world,

00:06:05

oil production began several centuries

00:06:08

ago and at first its storage was not

00:06:13

given such due attention,

00:06:16

since no one believed that oil at all

00:06:18

it is necessary to somehow carefully store in order to

00:06:22

store a large amount of experience of

00:06:24

the substance somewhere, small special bars were built

00:06:27

or simply prepared with a

00:06:30

depth of 4-5 meters, the floors in these places

00:06:34

were made of clay and the pits were covered with

00:06:38

stone folding roofs for a long

00:06:41

time,

00:06:42

this method of storing oil remained

00:06:46

the only one and was also used

00:06:49

in our country,

00:06:53

so the following

00:06:57

oil oil has a very complex

00:07:02

chemical composition and is a

00:07:05

mixture of hydrocarbons

00:07:09

and other compounds; the main

00:07:13

components of oil are methane,

00:07:16

naphthane and aromatic hydrocarbons

00:07:19

consisting

00:07:21

of

00:07:23

5 to 17 hydrocarbon atoms; the main

00:07:27

elements in the composition of oil are

00:07:29

carbon 187 percent hydrogen up to 14

00:07:33

percent, which means that among other

00:07:38

components of the oil composition there is

00:07:40

sulfur 6 percent nitrogen 0.3 percent

00:07:44

oxygen up to 73 percent

00:07:48

there is such a concept that exists: crude

00:07:52

oil and commercial oil The

00:07:56

fact is that crude oil is a natural

00:08:00

fossil part of a hydrocarbon that

00:08:03

contains gas dissolved outside water

00:08:05

mineral salt mechanical impurities and

00:08:08

commercial they are prepared for

00:08:12

delivery to consumers in accordance with the

00:08:16

requirements of current regulatory and

00:08:20

technical documentation

00:08:27

crude oil refers to oil obtained

00:08:31

directly

00:08:33

and wells at the exit from the oil reservoir

00:08:37

does not contain rock particles water as

00:08:40

well as salts dissolved in it, that is,

00:08:42

crude oil This is oil which we

00:08:45

obtain directly from wells. That is,

00:08:48

it contains particles of rock and so

00:08:52

on, these impurities cause corrosion of

00:08:55

equipment and serious difficulties

00:08:57

in transporting and processing

00:08:59

petroleum raw materials. Thus, for

00:09:02

export or delivery to remote

00:09:05

production sites, oil refineries

00:09:08

require industrial processing of oil,

00:09:10

that is, from it water is removed

00:09:14

mechanical impurities salts and solid

00:09:16

hydrocarbons gas is released gas and the

00:09:20

lightest hydrocarbons must be

00:09:22

separated from the oil since they

00:09:26

are valuable products

00:09:30

and can be lost during storage. In

00:09:32

addition, the presence of light gases during

00:09:34

transportation of crude oil can

00:09:37

lead to the formation of gas bags

00:09:40

purified from water from gas into crude oil

00:09:44

is supplied to oil refineries

00:09:46

and where in the process

00:09:48

various types of petroleum products are not received, the quality of

00:09:51

how the petroleum products obtained

00:09:55

is determined by its quantity

00:10:00

and where we have a video

00:10:04

video why there is no video

00:10:07

so it is not commercialized, it is a liquid from

00:10:11

light to brown

00:10:15

brown in color commercial is not a

00:10:18

mixture multiphase

00:10:20

means production

00:10:24

means when unraveling reservoir

00:10:27

oil

00:10:30

means during acceleration in the process of

00:10:33

lifting on the surface well

collection and field preparation system

00:10:38

to marketable condition part of the oil

00:10:41

evaporates oil gas

00:10:45

what oil is in general

00:10:48

oil It is liquid According to GOST

00:10:53

51 858 22 oil and general technical

00:10:58

conditions oil is a

00:11:00

liquid natural fossil mixture of

00:11:04

hydrocarbons of wide physical

00:11:06

composition. Now I told you the definition.

00:11:09

According to GOST, oil is a liquid

00:11:13

natural fossil mixture of

00:11:15

hydrocarbons of wide physical

00:11:18

chemical composition. Also according to this

00:11:20

GOST,

00:11:21

classification is defined

00:11:24

symbols in this guest main

00:11:26

properties labeling safe storage

00:11:30

environmental protection environment and

00:11:33

acceptance rules, testing methods for

00:11:36

transportation and storage

00:11:41

oil tanks are containers of

00:11:45

various sizes

00:11:47

designed for the accumulation of

00:11:50

short-term storage and accounting of crude

00:11:54

and commercial oil. This definition

00:11:58

means this is a container of various sizes

00:12:03

they are intended for accounting and storage of

00:12:07

commercial oil. A group of tanks

00:12:10

concentrated in one place is called

00:12:14

tank farm

00:12:20

Well, what can we say, the history of the

00:12:23

emergence of

00:12:24

the tank is connected with the development of the Baku

00:12:28

oil industry, which means that in the 17th century,

00:12:32

with the increase in oil production in Baku,

00:12:35

oil warehouses began to appear, that is, what are

00:12:39

small earthen tanks, pits in

00:12:43

clay soils, the

00:12:45

first steel

00:12:48

tank was built in

00:12:51

1878 according to Shukhov’s design in

00:12:58

1935 year, for the first time in Russia, a

00:13:03

metal welded tank

00:13:06

with a capacity of 1000 cubic meters was built; this

00:13:09

progressive method of construction

00:13:11

gained popularity

00:13:14

and made it possible to subsequently switch to the

00:13:18

Industrial method of manufacturing the

00:13:20

main parts of tanks; the

00:13:24

capacity of individual tanks

00:13:26

built in Russia reaches 50

00:13:29

cubic meters; work is also underway

00:13:32

to create a

00:13:33

capacity of one hundred cubic meters.

00:13:36

Industrial method assembling tanks

00:13:39

or the method of assembling from rolls of blanks

00:13:42

began to be used in the Soviet Union in the

00:13:45

60s of the last century.

00:13:48

This method was developed by the

00:13:51

Paton Institute of Electric Welding. This method of

00:13:56

manufacturing tanks practically

00:13:59

tested the sheet-by-sheet assembly method in the

00:14:03

Soviet Union. It was built

00:14:05

specialized

00:14:07

built and specialized for the production of

00:14:12

tank blanks several

00:14:14

factories in the Industrial method of

00:14:18

construction, factory conditions on a

00:14:21

special stand, the

00:14:24

panel is welded; the bottom of the body; and

00:14:27

the roof is made from accounts

00:14:30

shaped like sectors; the

00:14:33

panel of the body is

00:14:37

rolled into a roll during the welding process;

00:14:48

based on

00:14:51

the calculation that each roll does not exceed

00:14:53

the weight of the Railway wagon standard,

00:14:56

usually rolls are made weighing 45 tons

00:15:01

But no more than 6 tons, then factory

00:15:04

blanks are usually

00:15:06

delivered by rail.

00:15:11

Well, today the installation of

00:15:14

tanks and factory blanks is

00:15:16

currently carried out using

00:15:19

truck cranes with a large

00:15:22

lifting capacity,

00:15:24

so the following

00:15:27

So,

00:15:28

the

00:15:30

tank tank is translated from French as

00:15:35

save save. That is, it is a container

00:15:39

for storing liquids and gases.

00:15:44

Tanks for storing

00:15:47

petroleum products are classified

00:15:52

according to the materials of manufacture according to the shape of the

00:15:56

installation design in relation to the

00:16:00

ground according to the type of product stored.

00:16:05

What I want to say is that in the production of

00:16:08

tanks for petroleum products

00:16:10

chemical resistant chemicals are used

00:16:13

materials in Russia there are two

00:16:16

state standards that

00:16:19

regulate tanks for petroleum products:

00:16:22

GOST

00:16:24

17032 2010, these are horizontal steel tanks

00:16:28

for petroleum products, the

00:16:31

horizontal design is designed for

00:16:33

small ones from 3 to 100 cubic meters and

00:16:36

GOST 31 385 2016,

00:16:40

vertical cylindrical

00:16:42

steel tanks for oil and petroleum products, the

00:16:45

vertical design is designed for

00:16:47

larger volume from 100 to 120 cubic

00:16:55

meters So, the definition of a tank

00:17:00

is a container for storing liquids or

00:17:05

gases;

00:17:12

one of the main

00:17:15

classifications is the type of material from

00:17:19

which the tanks are made,

00:17:21

depending on whether they can be divided into

00:17:24

frame soft; to speak in more

00:17:27

detail, the tanks can be

00:17:30

reinforced concrete metal and

00:17:34

non-metallic reinforced concrete

00:17:36

are reliable but have a number of

00:17:39

disadvantages, including difficulties during

00:17:42

transportation; metal, with

00:17:44

suffering, which improves the best

00:17:47

non-metal alloys, which

00:17:49

includes plasticity;

00:17:52

fiberglass; also fabric

00:17:54

containers; equipment; and natural conditions,

00:17:57

that is, tanks in the creation of which are

00:18:00

used, which means

00:18:03

natural voids, be it Mines or something

00:18:06

else

00:18:07

what I want to say is that there is a

00:18:10

classification of tanks

00:18:14

classification of tanks classification they

00:18:17

can be

00:18:20

classified according to the following main

00:18:24

characteristics first by materials by the

00:18:29

material from which they

00:18:31

are made they can be

00:18:34

metal

00:18:36

reinforced concrete

00:18:37

stone earth

00:18:40

synthetic Lego soil and mountain in

00:18:46

various rocks that make up the

00:18:49

earth's crust that is, according to materials

00:18:53

materials

00:18:56

the following by the magnitude of excess

00:18:58

pressure by the magnitude of excess

00:19:01

pressure

00:19:04

low pressure tanks in which the excess

00:19:07

pressure differs little from atmospheric

00:19:11

and high pressure tanks low

00:19:15

pressure This is where it is less than 0.2

00:19:21

megapascal and more than 0.2

00:19:24

megapascal

00:19:26

the following

00:19:27

means by

00:19:30

technological operations These are

00:19:34

storage tanks low-viscosity oil and

00:19:37

petroleum products

00:19:39

storage tank for high-viscosity

00:19:41

oil and petroleum products

00:19:44

settling tanks tanks

00:19:47

mixers tanks of special

00:19:50

designs for storing oil and

00:19:53

petroleum products

00:19:56

means with high pressure of saturated

00:19:59

rocks once again means for technological

00:20:03

operations storage tanks for low-

00:20:07

viscosity oil and petroleum products storage tank for high-viscosity oil and petroleum products

00:20:10

highly viscous oil

00:20:13

and petroleum products tank settling tanks

00:20:17

mixer tanks and so on the

00:20:21

next fourth

00:20:24

means

00:20:27

by design by design there are

00:20:31

steel

00:20:33

tanks: vertical

00:20:36

cylindrical with conical and

00:20:39

spherical roofs

00:20:42

horizontal cylindrical with flat

00:20:44

and spatial bottoms drop-shaped spherical

00:20:48

cylindrical tanks

00:20:52

second

00:20:54

reinforced concrete tanks they are

00:20:57

vertical and horizontal

00:21:00

cylindrical there are rectangular and

00:21:04

trench

00:21:08

in

00:21:09

relation to the level of the Earth, which

00:21:13

means underground

00:21:16

underground When the highest level of

00:21:20

petroleum products in the tank is at

00:21:24

least 0.2

00:21:26

meters below the current one, it means the planning

00:21:32

marks of the adjacent site site,

00:21:37

that is,

00:21:39

having a

00:21:42

reference of at least

00:21:45

0.2 meters above the permissible highest

00:21:50

tank level is underground, that is, an

00:21:53

underground tank refers to containers

00:21:56

whose highest level of petroleum products is

00:21:59

lower than 0.2 lower than the planning

00:22:03

level adjacent areas within

00:22:06

three meters from the side wall of the tank

00:22:10

Well, the tank is above ground if

00:22:14

they differ from the above

00:22:20

conditions, that is, when the bottom is at the

00:22:24

same level or higher at the lowest level

00:22:28

it is planned at the level of the adjacent

00:22:30

site there are also semi-buried

00:22:36

the following

00:22:38

means by location it is divided into above-

00:22:41

ground underground and semi-underground I

00:22:51

would also like to say according to the classification the

00:22:55

dependence on the amount of

00:22:58

internal pressure tanks without

00:23:01

pressure this means spontaneous or

00:23:04

floating lid the second

00:23:07

low-pressure tanks are intended for

00:23:10

storage of products under excess

00:23:12

pressure up to 200 mm water of the internal

00:23:18

column and tanks with increased pressure for

00:23:21

storage of oil products under

00:23:24

excess pressure up to 700 millimeters

00:23:31

that is, by volume also tanks are

00:23:35

classified 100 200 300 and

00:23:39

so on

00:23:41

Now you see on the classification screen of an

00:23:44

oil storage tank and

00:23:47

petroleum products, that is, we have everything that we

00:23:49

said. We have now collected it in this

00:23:51

diagram. Here you see that in terms of

00:23:54

technological operations,

00:23:57

these are low-viscosity, highly evaporating

00:24:01

oils, highly viscous, highly solidifying

00:24:04

threads, as well as settling tanks,

00:24:08

mixer tanks, by design and

00:24:12

the material used, there are steel

00:24:16

tanks, vertical cylindrical,

00:24:21

stationary roofs with floating

00:24:24

roofs with pontoons can be

00:24:26

horizontal-cylindrical

00:24:29

spherical and teardrop-shaped, this is what

00:24:33

applies to steel tanks and reinforced concrete tanks,

00:24:36

these are made of

00:24:39

monolithic reinforced concrete and prefabricated

00:24:42

reinforced concrete, according to the amount of excess

00:24:45

pressure in the gas space,

00:24:47

tanks are divided into low-

00:24:50

pressure grain, high-pressure tank

00:24:53

depending on volume and

00:24:56

location they are divided into classes class

00:24:59

1 2 and 3

00:25:02

class 1 refers to Particularly dangerous

00:25:05

tanks with a volume of 10 thousand cubic

00:25:08

meters or more, as well as tanks with a volume of

00:25:12

5000 cubic meters or more

00:25:16

located directly along the banks of

00:25:18

rivers of large reservoirs, as well as

00:25:21

urban areas, class two these are

00:25:24

high-risk tanks with a volume of

00:25:27

5-10 thousand cubic meters, class 3, you

00:25:32

see this is our hazard class, dangerous

00:25:39

tanks with a volume from 100 to 5000

00:25:42

cubic meters.

00:25:44

Here you see a diagram of how

00:25:47

oil tanks are divided into

00:25:50

underground and partially buried ground

00:25:52

version, ground version,

00:25:56

we have steel ones which are

00:25:59

vertical-cylindrical divided by

00:26:00

wall design by roof structure

00:26:03

by pressure concrete and partially

00:26:07

buried these are reinforced concrete

00:26:09

cylindrical and rectangular

00:26:14

So you mean, depending on the volume we

00:26:18

talked about, it means first class second

00:26:21

and third depending on the volume and

00:26:23

location of the tank they are divided into three

00:26:27

classes the distance between tanks are

00:26:30

assumed to be equal for tanks with

00:26:33

floating lids 0.5

00:26:36

diameter for tanks with stationary

00:26:39

roofs on pontoons 0.65 diameter for

00:26:43

tanks with stationary roofs on

00:26:45

pontoons 0.75 diameter and another

00:26:49

definition Let's talk about the

00:26:51

operation of tanks and tank

00:26:55

farms - this is a set of processes

00:26:59

acceptance of storage and delivery of oil testing

00:27:05

acceptance of tanks into operation

00:27:08

maintenance and repair

00:27:13

So, oil storage tanks

00:27:16

are metal and non-metallic,

00:27:19

remember metal steel are

00:27:22

cylindrical vertical

00:27:24

cylindrical horizontal

00:27:26

special designs non-metallic

00:27:29

are reinforced concrete rubber fabric and

00:27:31

underwater means another division

00:27:35

that we talked about today is was this

00:27:39

is the shape of the tanks themselves, they

00:27:42

come in the following types: cylindrical

00:27:46

spherical and teardrop-shaped tank This is a

00:27:53

cylindrical shape, the most popular option

00:27:56

providing the ability to create

00:27:58

almost any capacity that does not

00:28:01

require special maintenance,

00:28:03

spherical is a more specific type of

00:28:06

oil storage tank, distinguished by a

00:28:09

round shape, the need to create a

00:28:11

special design teardrop-shaped

00:28:14

similar the form refers to those types

00:28:17

that are created so-called soft

00:28:20

tanks

00:28:25

Well, what else would I like to say, depending

00:28:28

on the material from which they

00:28:30

are made,

00:28:32

we said that tanks are divided

00:28:36

into metal,

00:28:39

metal and non-metallic

00:28:42

metal, of course they are built

00:28:46

from steel, sometimes from aluminum, non-

00:28:51

metallic include reinforced concrete

00:28:54

and plastic

00:28:57

tanks tanks are shaped vertically

00:29:00

cylindrical horizontal

00:29:03

drop-shaped rectangular

00:29:05

at an oil collection point they usually build

00:29:10

tanks with a volume of 2000 3000 10 thousand and

00:29:14

so on the total volume of the tank

00:29:16

farm depends on the planned indicators for

00:29:20

oil production from the water cut of the product

00:29:25

design standards according to the

00:29:29

installation scheme tanks are divided into above-ground

00:29:32

ones the bottom is at the level and

00:29:35

above the planning level of the adjacent

00:29:37

site underground When the highest

00:29:40

level of liquid, the tank is

00:29:42

below the planning level of the adjacent site and by at

00:29:45

least 0.2 meters,

00:29:48

the remaining tanks are built with a

00:29:51

constant or variable

00:29:55

body wall thickness, depending on the volume, the

00:29:58

height of

00:29:59

the tank is made of sheet steel,

00:30:03

grade 2 St3 with a thickness of 4 to 10 meters,

00:30:08

according to technological conditions,

00:30:13

sheet steel with a thickness of

00:30:15

less than 4 mm cannot be used in the manufacture of tanks, the

00:30:17

distance between tanks is assumed

00:30:22

to be equal for a tank with floating

00:30:25

lids, at least 0.5

00:30:28

diameter for tanks with stationary

00:30:32

roofs and pantones, 0.65 diameter

00:30:35

for tanks with stationary roofs but

00:30:39

without pontoons

00:30:40

0.75

00:30:43

operating diameter, as we have already said, the

00:30:47

totality of all processes

00:30:51

and tanks of medium and larger capacities, in

00:30:55

order to save material, are made with

00:30:58

variable wall thickness along the height of the

00:31:00

walls of vertical cylindrical

00:31:03

tanks in the absence of excess

00:31:07

pressure on the surface of the liquid,

00:31:11

they experience pressure

00:31:14

depending on the height of the column This

00:31:18

means underground. These tanks are a

00:31:22

type of horizontal reserves

00:31:25

used for storing petroleum products,

00:31:28

water and other liquids under various

00:31:32

excess pressures. The

00:31:34

tanks are buried in the soil or sprinkled with

00:31:37

soil, while the highest level of

00:31:39

liquid that is stored in the underground

00:31:42

tank is more than 0.2

00:31:51

m.

00:31:56

So, reinforced concrete tanks are

00:32:00

reinforced concrete

00:32:02

This means, as we said, zirvars are

00:32:05

metal; metal reinforced

00:32:08

concrete tanks are not

00:32:10

metal tanks; these are

00:32:13

tanks that have a supporting

00:32:18

structure made of

00:32:22

non-metallic materials; non-

00:32:25

metallic reservoirs include

00:32:27

lyso-concrete and a tank made of rubber bands,

00:32:30

fabric or synthetic materials

00:32:33

used with

00:32:35

the advantage of being mobile;

00:32:40

reinforced concrete tanks according to the type of

00:32:43

petroleum product stored are divided

00:32:46

into tanks for fuel oil, oils, and

00:32:51

light oil products, oil, and fuel oil; they

00:32:54

have virtually no chemical

00:32:57

effect

00:32:58

on concrete and have the ability, due to the

00:33:02

heavy fractions of resins, to plug

00:33:06

finely porous material, reducing

00:33:08

their leakage and permeability over time

00:33:12

when storing these products in

00:33:15

reinforced concrete tanks; they do not

00:33:18

require special protection of the walls

00:33:21

coating of the tank and during storage of

00:33:24

lubricating oils. In order to avoid their

00:33:27

contamination,

00:33:32

they protect the internal surfaces of the tanks with

00:33:35

various coatings and

00:33:38

lining also applies to tanks

00:33:41

for light, easily evaporating

00:33:43

petroleum products.

00:33:45

In addition, I would like to say that

00:33:48

reinforced concrete tanks, in addition to

00:33:51

saving metal, also have

00:33:55

technological benefits, mainly when

00:33:57

stored in In them, heated viscous oil and

00:34:00

petroleum products cool more slowly

00:34:03

due to small losses, and when

00:34:06

storing easily evaporating light

00:34:08

petroleum products, losses from evaporation are reduced.

00:34:11

Since tanks are

00:34:13

installed underground, they are less

00:34:15

susceptible to solar radiation, you see

00:34:19

semi-lifting oil storage tanks are

00:34:22

usually built from reinforced concrete tanks from 500

00:34:25

to 330 thousand cubic meters,

00:34:28

they are structurally

00:34:30

cylindrical rectangular with

00:34:32

prefabricated walls and a coating.

00:34:36

You see reinforced concrete in

00:34:39

the design in the figure, that is,

00:34:41

reinforced concrete tanks are subdivided

00:34:43

and used for nitrogen oil oils

00:34:47

light petroleum products durability

00:34:49

means the service life of reinforced concrete

00:34:52

tanks is 40-60

00:34:55

metal consumption per 1 liter cubic liter

00:34:58

capacity is reduced almost twice

00:35:00

the ability to store sulfurous oils and

00:35:04

petroleum products reduced heat exchange with the

00:35:06

environment reduction of

00:35:09

heat losses reduction of losses from evaporation of

00:35:11

products 5-10 times

00:35:15

bitumen leaks out of petroleum products

00:35:17

as a whole insignificantly and, which is characteristic,

00:35:21

fuel oil practically does not have a

00:35:23

chemical effect on concrete and

00:35:26

has the ability to heavy

00:35:28

fraction tampon finely porous

00:35:32

materials

00:35:34

Here you see rubber fabric tanks

00:35:38

rubber fabric tanks

00:35:43

they are a

00:35:47

closed shell,

00:35:52

which means a closed shell, installation of

00:35:55

reinforcement, the shell has the shape of a pillow,

00:36:01

consists of an internal

00:36:07

petrol-resistant

00:36:09

rubber layer,

00:36:14

which means a

00:36:16

nylon

00:36:18

power layer and an outer atmospheric

00:36:21

rubber what would you like to say

00:36:24

about these Jaguars in general? this is a soft

00:36:28

tank,

00:36:30

abbreviated as MR, these are polymer or

00:36:34

rubber-fabric tanks, often

00:36:36

having a pillow shape. As you can see

00:36:41

in the figure, they are designed for

00:36:44

storing and transporting various liquid

00:36:47

substances. soft tanks are

00:36:50

particularly flexible; low specific gravity;

00:36:53

high chemical and corrosion

00:36:57

resistance; they are used in

00:37:03

petrochemical, chemical and agricultural enterprises.

00:37:07

companies are Rubber fabric tanks

00:37:10

underground tanks This off-season is

00:37:14

used for off-season storage of

00:37:17

petroleum products,

00:37:19

underground tanks that are

00:37:22

built in rock salt deposits at a

00:37:25

depth of 100 meters and below are of great importance underwater

00:37:29

storage underwater storage

00:37:31

consists of or reinforced concrete designed

00:37:33

for storing oil at sea depths of up to

00:37:37

500 meters according to the degree of immersion there are

00:37:42

bottom floating according to the materials of

00:37:45

manufacture reinforced concrete elastic

00:37:48

rubber fabric and metal So a

00:37:52

horizontal steel tank

00:37:57

remember

00:37:59

rgs tank a horizontal steel

00:38:05

tank horizontal steel

00:38:10

means that here it is typical for this type to

00:38:14

include

00:38:17

tanks as

00:38:22

directly as the RGS tanks themselves

00:38:26

for storing oil product

00:38:31

and

00:38:33

oil settling tanks for natural

00:38:37

settling of the

00:38:39

oil emulsion All this

00:38:42

must necessarily be in accordance with GOST 17032

00:38:46

20 10 steel tanks

00:38:48

for them those products

00:38:51

horizontal tanks store already

00:38:55

processed oil or oil product

00:39:00

Well, what can we say about rgs these

00:39:04

tanks are widely used

00:39:07

for storing petroleum products

00:39:09

in small quantities

00:39:12

we will Considered

00:39:14

in comparison with vertical

00:39:17

tanks, the construction of

00:39:19

horizontal tanks consumes

00:39:22

one cubic meter more

00:39:25

metal;

00:39:27

the advantage of horizontal tanks

00:39:30

is the possibility of

00:39:32

their mass production at factories for the storage of

00:39:35

oil products under high excess

00:39:38

pressure and vacuum; convenience;

00:39:41

underground installations;

00:39:43

volumes of CGS from 3 to 200 cubic meters

00:39:48

Working pressure up to two and a half

00:39:51

megapascals, the bottom of the tanks

00:39:55

is made physical flat or

00:39:58

cylindrical

00:40:00

as follows.

00:40:02

So today, you

00:40:06

see, there are various options for storage,

00:40:10

for example, here you see a ground

00:40:14

floor, an underground underwater

00:40:16

and an

00:40:19

underground tank, this is all

00:40:22

depending on the location of the

00:40:24

tank,

00:40:26

ground When the entire tank is located

00:40:29

on the surface of the Earth,

00:40:31

semi-underground, when the main part of

00:40:33

the tank is in the ground and

00:40:37

only the neck comes out; completely

00:40:40

underground are intended for more complete

00:40:43

long-term storage, saving free

00:40:47

space and underwater,

00:40:50

as

00:40:56

you see, ball tanks mean ball tanks at

00:41:00

oil plants are used for storing

00:41:05

propane-butane fractions and also

00:41:08

as

00:41:10

electrodedrants in electrical installations have been used to

00:41:14

deplete oil; during their construction,

00:41:17

less metal is consumed than in

00:41:21

cylindrical horizontal devices;

00:41:23

spherical and drop-shaped tanks can be

00:41:28

used to store funds with

00:41:31

excess pressure of up to 0.2

00:41:35

Newton and higher;

00:41:39

the following means

00:41:43

drop-shaped tanks; drop-shaped

00:41:47

tanks are

00:41:50

called

00:41:51

tanks with a shape The shell

00:41:55

corresponds to the shape of a drop of liquid. The

00:41:59

design of such tanks is

00:42:02

based on the principle of equal strength of a shell of

00:42:05

constant thickness with full

00:42:08

use of the existing

00:42:11

capabilities of the shell,

00:42:13

since drop-shaped tanks during

00:42:16

operation are subject to various

00:42:19

combinations of loads depending on the

00:42:22

level of oil pressure in the gas

00:42:26

space; the profile is

00:42:28

equal to the strength of the shell of spherical

00:42:32

tanks; backgrounds are calculated more

00:42:35

load when the tank

00:42:38

is filled to the maximum level

00:42:42

for proper safety of

00:42:45

steel

00:42:47

above-ground tanks including the reception of

00:42:49

storage and release of petroleum products and so

00:42:52

on,

00:42:54

special equipment must be installed

00:42:57

which we will talk about tomorrow,

00:43:01

you see spherical tanks are

00:43:04

designed for storing

00:43:07

liquefied gases and liquids, a

00:43:10

very important point means it is

00:43:13

vertical

00:43:15

[music ]

00:43:16

steel tank

00:43:23

RVS tank we remember the first with the tank

00:43:27

vertical steel

00:43:29

tank RVS these are vertical

00:43:32

cylindrical steel tanks with a

00:43:35

nominal volume from one hundred to 120 thousand

00:43:40

cubic meters it is also possible to

00:43:43

design and manufacture RVS with a

00:43:46

volume of more than 120 thousand according to

00:43:49

individual

00:43:51

technological conditions the location of

00:43:54

these tanks ground seismicity of the

00:43:58

construction area no more 9 points

00:44:02

inclusive The

00:44:04

maximum temperature of the

00:44:07

tank body is no more than 100 degrees The

00:44:13

minimum temperature of the

00:44:15

tank body is not less than minus 60 degrees

00:44:19

Celsius

00:44:21

Currently,

00:44:23

oil refineries

00:44:25

use vertical steel

00:44:27

tanks with a nominal capacity of 100 to

00:44:32

50 cubic meters, which means the

00:44:37

method of manufacturing and installation of sheet

00:44:40

metal structures is in in roll

00:44:43

form,

00:44:45

tanks are roll assemblies for which

00:44:48

sheet structures, walls, panton bottoms

00:44:52

and roofs are manufactured and installed in the form of

00:44:56

rolls,

00:44:58

which means in roll form, it also

00:45:01

happens in sheet form, when

00:45:05

tanks are in sheet assemblies, that is, the

00:45:08

production and installation of

00:45:12

all sheet structures that

00:45:14

are made from individual sheets also happens,

00:45:18

which means combined performance

00:45:20

tanks are combined assemblies, the walls

00:45:24

of which are made and assembled from

00:45:27

separate sheets and sheet structures

00:45:30

with a fixed roof, floating

00:45:33

roofs or pontoon Wiki roll

00:45:36

sheets

00:45:38

according to their purpose, which means

00:45:43

tanks are raw materials for storing

00:45:47

crude oil, according to their purpose there are also

00:45:51

process tanks This is for the

00:45:54

discharge of Layers of sludge water and

00:45:58

oil commodity for storing oil according to the

00:46:03

method of manufacturing the belts, the

00:46:06

belts are welded, the joint is welded in steps, or a

00:46:10

telescopic one is made.

00:46:15

So you see vertical tanks

00:46:18

for storing liquids,

00:46:22

vertical tanks, ground-based

00:46:25

volumetric

00:46:27

building structures are designed

00:46:29

to receive storage, oil accounting,

00:46:34

what else is important for vertical

00:46:38

cylindrical tanks, depending

00:46:41

on the volume of protected stored product

00:46:45

vertical cylindrical steel

00:46:48

tanks for them, oil products

00:46:52

are divided into 4 hazard classes,

00:46:56

class one, tanks with a volume of more than

00:47:01

50 thousand cubic meters, class two

00:47:05

tanks with a volume from 20 inclusive to 50

00:47:10

thousand cubic meters included, and also a

00:47:13

tank with a volume from 10 to 50 thousand

00:47:17

cubic meters inclusive

00:47:19

is located directly along shore of

00:47:22

large volumes of urban

00:47:24

development class 3 is a tank with a volume

00:47:28

of

00:47:29

1,120,000 class 4 a

00:47:32

tank with a volume of

00:47:34

1000 cubic meters the hazard class of

00:47:39

tanks must be taken into account when

00:47:42

designating, that is, with a

00:47:45

reliability coefficient for responsibility of

00:47:47

special requirements for materials by

00:47:49

manufacturing method volumetric quality control

00:47:54

Let's summarize a little and highlight

00:47:59

for reception of oil storage accumulation,

00:48:03

vertical cylindrical

00:48:06

steel reinforced concrete tanks

00:48:09

of the following types are used

00:48:11

RVS rvsp

00:48:14

rvspk first SPA volume from 100 to 50

00:48:19

thousand cubic meters

00:48:21

reinforced concrete reinforced concrete tank volume from 500 to 30 thousand types

00:48:27

volume used in accordance with

00:48:30

state standards design documentation Here you

00:48:33

see means volumes type dimensions

00:48:36

dimensions type volumes wall height and

00:48:41

diameters of

00:48:44

these tanks

00:48:46

structural elements of steel

00:48:48

vertical these are the main structural

00:48:51

elements these are load-bearing fencing

00:48:54

reconstruction load-bearing structures wall insert pipe hatch outskirts bottom

00:49:01

frameless frames ring

00:49:04

anchor fastenings of walls rings burns this is

00:49:08

all of them load-bearing structure enclosing

00:49:11

structure this means the Central part of

00:49:13

the bottom is the flooring permanently this is a

00:49:15

floating roof and panton stairs and

00:49:19

fencing platforms are classified as

00:49:23

auxiliary structures So this

00:49:26

means that metal vertical

00:49:30

cylindrical tanks

00:49:34

RVS is divided

00:49:39

into a sonar

00:49:41

tank with a

00:49:43

roof without

00:49:46

pontoon a

00:49:48

tank with a

00:49:50

stationary roof with Anton a

00:49:53

tank with a floating roof roof

00:49:58

tanks So the tank with a pontoon you

00:50:02

see in the picture is a variant of the

00:50:04

vertical cylindrical a

00:50:06

stationary roof tank, which is used

00:50:09

when there is a large

00:50:10

turnover of oil and petroleum products to

00:50:13

reduce their losses during their execution,

00:50:17

that is, from tanks with pontoons, these

00:50:22

tanks are used to reduce

00:50:25

losses of oil and petroleum products from

00:50:29

evaporation. The

00:50:30

panton is built into a

00:50:33

stationary tank with a panel roof that

00:50:36

protects against

00:50:39

precipitation on the surface of the pontoon pontoons in

00:50:44

tanks come in both metal

00:50:47

and synthetic

00:50:49

materials; the

00:50:52

buoyancy of metal plankton

00:50:54

is ensured by

00:50:56

a device on it along the

00:51:00

sealing contour of boxes or open

00:51:03

compartments.

00:51:05

Here we see

00:51:11

the SPC, so you see in the figure a

00:51:16

general diagram where the frame

00:51:21

itself means the

00:51:24

roof frame; you see

00:51:28

intermediate rings of rigidity. You also

00:51:32

see see the ring

00:51:36

here The central part of the

00:51:41

panton

00:51:44

support posts

00:51:46

reinforcing closures Here you see

00:51:50

the stairs and here is the floating roof

00:51:57

RVS - this is a steel tank without a roof a

00:52:02

vertical steel tank with a

00:52:05

stationary roof without a pontoon

00:52:08

is used for storing products with

00:52:11

relatively

00:52:12

low volatility

00:52:15

ignition temperature of more than 61 degrees most

00:52:20

often used for storage fuel oil

00:52:24

if household

00:52:27

Kerosene and so on

00:52:34

roof frame

00:52:37

sealing ring

00:52:40

intermediate rings and here is the central

00:52:43

bottom the next first joint venture is what we

00:52:48

said the first joint venture stands for a

00:52:53

vertical tank with a steel

00:52:57

stationary roof and a pontoon,

00:53:06

most often they store

00:53:10

gasoline and kerosene in a non-type fuel A pontoon

00:53:13

is rigid

00:53:15

gas-tight floating coating in

00:53:19

the form of a disk

00:53:20

[music]

00:53:21

which we place on the mirror with the product

00:53:25

inside a cylindrical tank

00:53:28

RVSP

00:53:29

tank vertical steel

00:53:33

stationary roof and pantoon

00:53:35

here the Pontoon is located inside the

00:53:39

tank on the surface of the liquid

00:53:43

data The Pontoon is designed to

00:53:46

reduce loss from evaporation

00:53:48

excluding the possibility of

00:53:51

explosion and fire

00:53:53

floating Pontoon was specially

00:53:57

manufactured to reduce the loss of

00:54:00

petroleum product that occurs during the evaporation of

00:54:04

products during storage

00:54:08

of the tank, the level of loss reduction

00:54:11

is reached 95

00:54:14

to 98,

00:54:16

depending on the stored product and the

00:54:19

operational

00:54:21

operational facts of the RVSP, that's

00:54:27

what we talked about here is the pontoon,

00:54:31

you see here the stands, the

00:54:34

sealing gate and the

00:54:37

first SPK

00:54:43

vertical steel tank with a

00:54:46

floating roof

00:54:50

means

00:54:52

this design of the tank

00:54:54

represents the use involves the

00:54:57

use of a roof located on

00:54:59

the surface of the stored product with full

00:55:02

contact

00:55:03

tanks with a floating roof in terms of

00:55:06

steel consumption are 20 percent less

00:55:09

metal intensive than tanks with

00:55:12

fixed roofs and losses from

00:55:15

evaporation are reduced by approximately 95 to

00:55:20

95 percent are especially appropriate the

00:55:24

use of these tanks for

00:55:26

sulfurous petroleum products since,

00:55:30

due to the absence of a gas space,

00:55:32

corrosion from the decomposition of sulfur compounds is

00:55:35

practically absent. This means that

00:55:39

floating roofs are made of steel

00:55:42

sheets with a thickness of at least 4 millimeters;

00:55:46

floating roofs come in two

00:55:50

types: double

00:55:53

pontoon, consisting of a number of

00:55:55

hermetic compartments and single with a

00:55:59

central disk made of steel sheets along the

00:56:03

periphery which are located in a

00:56:05

ring, here is a

00:56:12

metal one

00:56:15

with a floating roof orlysy. They do not have a

00:56:20

stationary covering; they are installed in the

00:56:24

southern middle zone with a small snow

00:56:26

load of a floating roof.

00:56:37

roof of the tank

00:56:43

here is the

00:56:44

rvspk here you see the ladder

00:56:50

You also see the floating

00:56:53

roof itself the floating roof also The upper ring of

00:56:57

rigidity the service platform here is

00:57:02

the schematic

00:57:04

vertical the rest of the floating roofs

00:57:08

here are the floating roofs

00:57:14

for cleaning inspection

00:57:16

special rolling ladders are used with one

00:57:20

end resting through the hinged upper

00:57:23

platform of the tank and the other

00:57:27

horizontally rail laid on a

00:57:30

floating roof

00:57:32

Here you see a diagram of a tank with a

00:57:35

floating roof

00:57:41

and that means

00:57:43

tanks with a protective wall

00:57:48

are called such tanks

00:57:53

glass in a glass

00:57:57

Well, what I want to say is that there is a

00:58:00

trend all over the world to

00:58:01

increase the number and size of tank

00:58:05

structures and which leads to an

00:58:09

increase in the liability of the danger of these

00:58:12

structures by one One of the possible

00:58:15

options for reducing the risk of accidents and

00:58:17

reducing the consequences is the

00:58:18

use of design schemes

00:58:21

that provide for the impact of a

00:58:24

protective wall around the main tank,

00:58:27

and one of the options for increasing

00:58:31

reliability could be a tank made of two

00:58:35

walls, such as a glass in a glass, the presence of a

00:58:39

ring protective wall of this

00:58:42

tank allows you to hold the product

00:58:46

in the event of an accident or violation of the

00:58:48

tightness of the main internal

00:58:51

tank and leads to a decrease in the

00:58:53

amount of aqueous solution forming

00:58:57

these means necessary to extinguish an

00:59:01

emergency fire; the same oil product

00:59:04

ends up in the annular gap, which

00:59:08

reduces losses

00:59:12

and reduces the lining area; the

00:59:16

tank has a double bottom to

00:59:19

allow

00:59:21

control of

00:59:22

possible leaks of liquid fuel; all this is

00:59:25

subjected to a

00:59:27

cylindrical all this confirms the

00:59:31

reliability and environmental safety of

00:59:33

vertical cylindrical tanks of the

00:59:36

protective wall.

00:59:39

Here you see a

00:59:41

schematic

00:59:43

diagram of the

00:59:45

main

00:59:47

main walls. You also see the protective

00:59:51

wall. Uh-huh.

00:59:54

Well, storage reception, accounting for the storage of

00:59:57

fire or drinking water, and so on.

01:00:01

This is the application and classification in the

01:00:06

sheet version combined

01:00:08

design according to the intended purpose raw materials

01:00:10

technological and commercial according to the

01:00:13

manufacturing method welded belts

01:00:16

stepwise welded the joint made

01:00:19

telescopically What else would you like to say?

01:00:22

When we talk about the

01:00:25

purpose of tanks, it is very important that

01:00:29

when they talk about the classification of

01:00:31

tanks, that

01:00:33

oil tanks are divided into

01:00:36

technologically, that is, what are

01:00:39

tanks for? are needed to break up the

01:00:44

oil emulsion and discharge formation

01:00:47

water

01:00:49

these are called

01:00:53

process tanks and commodity commodity

01:00:57

tank this is a tank designed

01:01:00

for storing dehydrated desalted

01:01:03

oil a

01:01:05

tank farm containing a commodity

01:01:08

tank is called a commodity park so

01:01:12

here please remember the code

01:01:16

word pay attention to everyone everyone

01:01:18

write down the code word

01:01:22

code word oil

01:01:26

so

01:01:28

if

01:01:32

I have any questions here, there should be two videos,

01:01:35

something isn’t there, I can turn it on

01:02:10

tomorrow. Tomorrow we will talk about

01:02:12

equipment

01:02:15

and once again I want to remind you that the

01:02:20

main course is maintenance,

01:02:22

current repairs of tanks and

01:02:24

tank farms, which will take place on the 12th

01:02:26

until September 14,

01:02:29

23 there is a discount If you

01:02:34

subscribe there is a 20 percent discount until September 4

01:02:44

so

01:02:45

the code word is no I draw your attention

01:02:54

not to the video as if Connect

01:09:02

like this Hello guys questions here I

01:09:05

saw a question about the service life of the

01:09:08

environment I didn’t understand at all maybe it would be

01:09:11

more correct to say And the service life of the

01:09:13

tanks, depending on the design of the

01:09:16

configuration, the tanks may have

01:09:19

internal external anti-corrosion

01:09:21

coating heating external protective skin,

01:09:24

all this affects the service life of the

01:09:27

tanks under favorable conditions,

01:09:30

which means the service life of tanks and

01:09:34

containers can reach 30 years or more.

01:09:47

So, what other questions?

01:10:03

Goodbye all

01:10:49

the certificate for listening to the webinar

01:10:51

will be I don’t know

01:10:58

which ones How to understand Wednesday that

01:11:03

you are the capacity

01:11:33

guys thank you very much for your attention

01:11:36

Goodbye and if you have any questions, write

01:11:39

tomorrow we will discuss more Have a nice

01:11:43

good day Goodbye
