What is pressure?
Pressure is the force acting per unit area. The pressure is denoted by the Latin letter R.
P = F/S,
where F is the force, N (kgf);
S - area, m 2 (cm 2).
Pressure can be: atmospheric (barometric), absolute (true), excess (gauge).
Atmospheric pressure is the pressure exerted by the atmosphere on all objects in it. It is balanced by a column of water with a height of 10m33cm or a column of mercury with a height of 760mm at a temperature of 0 o C. It is also called the physical atmosphere and is denoted: atm (1atm = 760mm Hg = 101080Pa)
Absolute pressure is the sum of atmospheric pressure and gauge pressure.
Rabs = Ratm + Rizb
For example, the pressure in a boiler, tank, or cylinder plus the pressure of the ambient air. Absolute pressure is measured in kgf / cm 2 (MPa).
Excess pressure is the pressure of steam inside a boiler or gas inside a cylinder, tank, without taking into account the pressure of the surrounding air. Excess pressure is measured and denoted by kgf/cm 2 (MPa).
In a technical system, an atmosphere (at) is taken as a unit of pressure - this is a force of one kilogram acting on an area of ​​\u200b\u200bone square centimeter (1at \u003d 1kgf / cm 2).

Physical and chemical properties of liquefied gas
Combustible gases used in vehicles are of two types:

natural;
artificial.

The source of obtaining a propane-butane mixture (С3Н8 - propane; С4Н10 - butane) is oil. Propane-butane mixture (PBS) belongs to the group of liquefied gas, because with an increase in pressure and a decrease in temperature, it passes into a liquid state with a multiple decrease in volume (250 times). The boiling point of propane is minus 42°C, and the boiling point of butane is minus 0.5°C.
PBS must meet the requirements of GOST 27578-87:
1. winter mixture PA (auto) 90±10% propane;
2. PbA summer mixture (auto) 50±10% propane, and the rest is butane;
3.liquefied gas should be smelled when the room is gassed
0.5% by volume;
4. liquefied gas is purified from hydrogen sulfide, leaving it 0.003% by volume.
5. The upper explosive limit of ERW is the maximum content of combustible gas in a mixture with air at which an explosion from an external source of ignition is possible.
Lower explosive limit LEL - the minimum content of combustible gas in a mixture with air at which an explosion from an external source of ignition is possible.
Explosive limits:
Propane: 2.3 - 9.5%
Butane: 1.9 - 8.5%
6. Gas density - propane = 2 kg / m 3; butane \u003d 2.7 kg / m 3
7. Relative density is the density of a gas relative to the density of air:
proran = 2: 1.29 = 1.55, butane = 2.7: 1.29 = 2.01

POSITIVE PROPERTIES OF LIQUEFIED GAS
Positive properties regarding gasoline:

gas is cheaper;
the car works environmentally friendly, CO is less;
higher octane rating than gasoline
oil changes less often, i.e. less polluted;
convenient for transportation, because from one volume of liquid, 250 times more gas formation is obtained.

NEGATIVE PROPERTIES OF LIQUEFIED GAS

when the room is filled with liquefied gas vapor from 2-9% of the volume and when a source of fire is introduced, an explosion will occur
in the event of a gas leak without a source of fire, liquefied gas vapors fill the lower layers of the room, because By specific gravity 2 times heavier than air. A person in such an atmosphere dies of suffocation;
liquefied gas during incomplete combustion releases carbon monoxide (CO-carbon monoxide), which has a negative effect on the human body, because. CO combines with the blood faster than oxygen. 1% CO is a lethal dose for humans. Asphyxiating gas is a leak, and poisoning occurs when the gas is burned, i.e. substances released during the combustion of liquefied gas.
Liquefied gas has a large coefficient of volumetric expansion compared to water, 11-16 times higher. Therefore, gas storage vessels are filled to 85% to avoid their bursting pressure.
Liquefied gas in contact with open area body in a liquid state freezes this area due to the absorption of heat. This is called a chemical burn. Rinse with plenty of cold water

Design features of AGZS.
The stationary gas filling station contains a stationary tank 1, a gas dispenser 7, a centrifugal pump 22 connected to the tank and a column, a control panel 17, as well as a system for draining, suction and injection of LPG.
The stationary tank 1 is equipped with two safety valves 3 located in its upper part, a pressure gauge and an LPG level indicator, connected to the control panel 17. The LPG drain system contains a transport tank 2, which is connected to the stationary tank through drain and equalizing hoses.

The suction system includes a pump 22 with an electric motor 20 connected through an electrical circuit with a control panel 17, and a suction line equipped with a shut-off valve 26, a pressure gauge 25, a gas filter 24 and a pressure gauge 23.
The injection system contains a pipeline 8 with an electric valve 6 connected to the control panel, and an oil separator 19.
The geyser 7 has a base 11 placed on a rigid foundation 12, an electric gauge 18, a gas meter 10 indicating the amount of gas filled and its cost, a degasser 9, a pressure regulator 16 and a flexible hose 14 with a filling device 13.
The degasser 9 ensures the separation of the liquid and gaseous phases of LPG. The vapor phase enters the pipeline 4 and returns to the stationary tank 1. The pressure regulator 16 is equipped with a high-speed valve 15 and communicates with the degasser 9 and the filling hose.
Safety valve 3 ensures that the vapor phase is discharged into the atmosphere. Line 8 liquid phase electric pump unit H4-5/170-1 is equipped with two shut-off valves. Line 4 of the vapor phase AGZS contains a mechanical valve and an electric valve communicated with the control panel 17.

The serviceability of the shut-off valves on the tank is checked by external inspection. Valves should be opened smoothly, without causing hydraulic shocks. Preparation for unloading and unloading of LPG from a gas truck into the gas filling station tanks is carried out by cylinder fillers and repairmen under the guidance of a shift foreman. During the drain operation, at least two people of the filling station service personnel must be present.
Prior to the start of LPG draining from the gas truck tank, the service personnel of the filling station must perform the following preparatory work:
secure the autogas carrier with special wooden shoes or shoes made of non-sparking metal;
make sure that the flexible hoses for draining the LPG from the tank are in good condition and reliable;
ground the tanker.
The permission to drain the LPG from the gas truck tank is issued by a shift foreman, who also gives orders to the persons employed at the drain to perform certain operations to prepare and carry out the drain of the LPG.
Draining of LPG from the tanker of an autogas carrier into the tanks is allowed only after the shift foreman and maintenance personnel are convinced of the correct opening and closing of the valves associated with this technological operation.
Draining operations must be carried out by personnel in standard work clothes, headgear and goggles.
Draining LPG from autogas carriers at gas filling stations is carried out by one of the following methods:
creation of the necessary pressure drop between the gas truck tank and the tank by pumping the LPG vapor from the tank of another group into the tank truck by the compressor;
creation of a pressure drop between the gas truck tank and the tank by heating the LPG vapor in the evaporator;
pumping LPG pumps;
by gravity, when the tanks to be filled are located below the tank car.
It is forbidden to create a pressure difference between the gas truck tank and the tank by releasing the vapor phase of gas from the tank being filled into the atmosphere.
The pressure of the vapor phase injected by the compressor or created by the evaporator in the gas truck tank must not exceed the operating pressure indicated on the gas truck tank plate. When the pressure in the gas truck tank rises above the working one, the compressor or evaporator must be immediately turned off. The pressure drop between the gas truck tank and the tank, as a rule, is allowed 0.15-0.2 MPa (1.5-2 kgf / cm2). When draining LPG from the tanks of gas carriers, the operation of the engine of the gas carrier is prohibited. After completion of the preparatory operations for draining the LPG and checking the gas truck by the service personnel, before removing the seals from the drain fittings, the driver of the gas truck is obliged to hand over the ignition keys to the gas filling station shift foreman.
It is prohibited for the driver of an autogas carrier to be in the cab during the LPG drain.
It is allowed to remove the plugs from the drain fittings of the gas truck tank only after the engine of the gas truck is stopped, and it is allowed to turn on the engine only after disconnecting the hoses from the process gas pipelines of the gas filling station and installing plugs on the drain fittings. After draining the LPG, the vapors should be removed from the tanks of the autogas carrier to a pressure of 0.05 MPa (0.5 kgf/cm2).
Discharge of gas into the atmosphere is prohibited.
During the LPG drain, it is prohibited for service personnel who are not involved in the drain operations to be near the gas carriers.
It is forbidden to keep tankers of autogas carriers connected to the technological gas pipelines of gas filling stations when the LPG is not drained.
The personnel involved in draining are obliged to monitor the tightness of all connections of technological gas pipelines, tanks and tanks of autogas carriers. If a gas leak is detected, the emergency section is turned off and measures are taken to eliminate it. During the LPG drain, it is forbidden to carry out any work to seal the joints under pressure; it is only allowed to disconnect the flexible hoses of the gas truck only after the tank has been turned off and the pressure in the drain hoses has been relieved. It is strictly forbidden during LPG draining to leave unattended the gas carrier tank, drain gas pipelines, tanks, operating compressors, pumps and evaporators.
During the period of draining, continuous monitoring of the pressure and level of gas in the tank car and the receiving tank must be ensured.
The tanks are filled with LPG to no more than 85% of their geometric volume. In case of tank overflow, the excess gas must be drained into other tanks. The release of excess gas into the atmosphere is prohibited.
Draining operations of LPG at filling stations during a thunderstorm, as well as during hot work in the production area, are prohibited.
During the LPG drain period, visual communication should be provided between the personnel servicing process gas pipelines and equipment (drain columns, compressors, pumps and evaporators). At the end of the drain, the valves on the gas truck tank must be plugged with plugs and checked for leaks with a soapy emulsion. Rubber-fabric sleeves (hoses) of autogas tankers must be attached to the drain tip with steel clamps (at least two clamps for each end of the hose). Wire clamps are not allowed.
Draining LPG is prohibited if the sleeves (hoses) have cracks, fractures, potholes and other damage and consist of separate parts.

Safety measures during survey of tanks
Tanks before internal inspection, hydraulic testing, repair or dismantling must be freed from gas, unevaporated residues and carefully processed. The release of tanks by discharging gas through a candle into the atmosphere is not allowed. The burning of the vapor phase residues should be carried out on a "candle" made of a steel pipe with a diameter of 20 mm, a height of 3 m and installed on a stable tripod in a fireproof place at a distance of 10-12 m from the border of the tank installation with an inclination of 50-60 ° to the horizon. Filling the tank with water should begin at the moment when the flame on the "candle" decreases to 20-30 cm, while the combustion of the vapor phase displaced by water should continue until the flame goes out.
The water supply must be stopped when the tank is full.
Processing of tanks should be carried out after disconnecting them from the gas pipelines of the vapor and liquid phases using plugs. Tanks should be treated by steaming and purging with an inert gas or filling with warm water. The quality of the degassing should be checked by analyzing air samples taken from the bottom of the vessel. The concentration of the LPG sample after degassing should not exceed 20% of the lower flammability limit of the gas. Depressurization of tanks without first reducing the pressure in them to atmospheric, as well as the use of air for degassing, are not allowed.
Work inside the tanks should be carried out by a team of at least three people under the supervision of a specialist in compliance with the following basic safety measures:
simultaneous descent into the tank by more than one person is prohibited;
the person working in the tank must have a hose gas mask and put on a rescue belt with a signal-rescue rope attached to it;
outside the tank there should be at least two people who should hold the ends of the ropes in their hands, observe the worker in the tank, be ready to provide him with the necessary assistance and not allow unauthorized persons to the place of work;
the residence time in the tank should not exceed 15 minutes;
the work team must be equipped with special protective equipment, special tools and explosion-proof flashlights;
every 30 minutes, check the tank for gas contamination with a portable gas analyzer. If a gas concentration above 20% of the lower flammable limit is detected, work in the tank should be stopped, people should be removed and re-degassing should be carried out, followed by a gas check.
During work in the tank, persons who are not related to these works are prohibited from being near the tank.
Sediments removed from the tanks must be kept moist and immediately removed from the territory of the gas filling station for disposal in a specially designated place. Sections of gas pipelines with pyrophoric deposits must be dismantled and stored in a safe area on the day they are opened. Water after washing and testing of tanks should be discharged into the sewerage system only through settling tanks, which exclude LPG from entering the sewerage system, or taken out to places determined by the sanitary and epidemiological supervision. The tanks must be put into operation after examination or repair on the basis of the written permission of the head of the enterprise (organization, etc.) of the gas filling station.
