The invention relates to the oil industry and can be used for the separation of oil and gas in the system of collection and preparation of production wells.

Known gas-liquid separator comprising a vertical cylindrical casing, thuja separator chamber [USSR Author's certificate No. 1254606, CL 01 D 45/12, 1982].

The disadvantage of the invention is the low efficiency of the separation of gas-liquid mixture.

Closest to the claimed design is the gas-liquid separator (hydrocyclone apparatus) comprising a vertical cylindrical casing, pipelines for supplying gas-liquid mixture, a gas outlet and a liquid drain pipe, a partition separating the separator on the camera, it is equipped with gas equalizing pipe (pipe) connecting the chassis (gas cavity under conical partition) separator with pipeline gas outlet, a partition in the housing of the separator is made conical, one camera - input, fitted with drain pipes and concentric installed kapitbahay camera with swirl, cone bottom and drain pipes, the lower ends of which are located below the ends of the drain pipe inlet chamber and installed in Gidrostroy glass in the lower part of the body. Gidrostroy glass provided with ribs on the outer surface and made of a height not less than the upper liquid level in the separator [RF Patent 2190450, CL 01 D 19/00, 45/12, published 27.07.2002].

For reasons that impede the achievement of specified following technical result when ispolzuet due to the fact, that:

- small amount of liquid gas-liquid separator for settling and liquid separation of gas bubbles;

- conical bottom inlet of the separation chamber and concentric installed kapitbahay camera with swirl reduce the volume of the gas-liquid separator for pre-separation of free gas;

- swirl installed in kapitbahay the camera is calculated for a certain range of gas flow rates outside this range increases the pressure drop, and this requires an increase in the stock of liquid level in the trap;

- placement of the drain pipes at different levels reduces the potential level of the gate, and this, in turn, reduces the supply of differential pressure required to prevent breakthrough of the gas in the liquid level;

- gas equalizing pipe connecting the gas passage under conical partition in the separator with pipeline gas outlet, does not provide a sufficient degree of removal of gas evolved from the liquid;

- narrowing of the area of the fluid passage in hydrostorm glass reduces the performance of the gas-liquid separator and creates the possibility of accumulation of solids.

The technical result that can be obtained when asresults is achieved by that separation installation comprising a vertical hydrocyclone apparatus pipelines supply gas-liquid mixture, a gas outlet and a liquid concentric installed kapitbahay chamber and gas equalizing pipe, while the hydrocyclone apparatus is installed in a horizontal technological capacity, the lower end resting in the interfaces with the cylindrical shell of technological capacity, the lower end of kapitbahay camera is on the same level with the lower end of the hydrocyclone apparatus, exhaust pipe line the bottom end set at the level corresponding to the upper generatrix of technological capacity, and gas equalizing pipe one end of which is placed in the gas cavity technological capacity, the other is in the axial zone of the gas exhaust pipe, in addition, between the gas equalizing pipe and the maximum liquid level horizontal technological capacity placed bumpers to prevent brythons in the exhaust pipe line.

Placing the lower end of the hydrocyclone apparatus based at the point of coupling with the cylindrical shell of technological capacity and placement of the lower end of kapitbahay camera on tneed, prevents the passage of gas to liquid and Vice versa, the passage of liquid in a gas line.

Connection gas equalizing pipe gas cavity technological capacity with axial area of the gas exhaust pipe increases the pressure drop reduction required for the water seal, and reduces the probability of ejection of the liquid in the gas line and hit a gas to a liquid through an injecting effect and removal of the emitted gas from the process vessel.

The establishment of the gas exhaust pipe lower end at the level corresponding to the upper generatrix of technological capacity, leads to equalization of pressure between the gas cavity technological capacity and axial area of the gas exhaust pipe that allows you to increase Gidrostroy difference between the liquid level in the processing tank and the exhaust pipe, and this prevents breakthrough of gas from the inlet cavity vertical hydrocyclone apparatus in the gas cavity technological capacity.

The drawing shows a separation system, General view.

The separation system includes a horizontal technological capacity 1, in which is placed a vertical hydrocyclone apparatus 2 to the pipe 3 input Noah technological capacity 1. Concentric hydrocyclone apparatus 1 is installed kapitbahay camera 4, the lower end of which is flush with the lower end of the hydrocyclone apparatus 2. Exhaust pipe line 5 bottom end set at the level corresponding to the top horizontal of the process container 1. The installation is also provided with a gas equalizing pipe 6, one end of which is placed in the gas cavity technological capacity 1, the other moves in the axial zone of the gas exhaust pipe 5. Between gas equalizing pipe 6 and a maximum liquid level horizontal tank 1 is placed bumpers 7 to prevent brythons in the exhaust pipe 5. Separated liquid is discharged through pipe 8.

Separation system operates as follows.

Gas-liquid mixture (SHC) is fed tangentially through the inlet 3 in the vertical hydrocyclone apparatus 2, where the separation of the SHC, with free gas separated from the liquid and rises upwards, continuing the rotation, to the open end of kapitbahay camera 4, and the liquid flows down the wall of the hydrocyclone apparatus 2. In kapitbahay chamber 4, the gas continues rotation when it is divided to the bottom and into the exhaust pipe 5. At the same time, the gas separated in the horizontal process vessel 1 via the gas equalizing pipe 6 enters the exhaust pipe 5. To prevent brythons in the exhaust pipe 5 between the gas equalizing pipe 6 and the maximum liquid level in the horizontal tank 1 has a bump 7. Separated liquid discharged through the nozzle 8.

The use of the proposed separation plant will:

- to increase the amount of sedimentation and to improve the quality of separation of liquid and gas by separating the bubbles of free gas in the processing vessel;

- increase the separation efficiency of gas-liquid mixture, to increase the level of the trap, thereby to prevent the passage of gas in the liquid and, on the contrary, the passage of liquid in a gas line;

- to increase the destruction of the emitted gas from the process vessel through an injecting effect;

to prevent brythons in the exhaust pipe placement of the bumpers between the gas equalizing pipe and a maximum liquid level of horizontal tanks;

- to exclude the possibility of accumulation of solids in horizontal tanks, without reducing the flow area for the flow of gidrol tereasa vertical hydrocyclone apparatus pipelines supply gas-liquid mixture, removal of gas and liquid, concentric installed kapitbahay chamber and gas equalizing pipe, wherein the hydrocyclone apparatus is installed in a horizontal technological capacity, the lower end resting in the interfaces with the cylindrical shell of technological capacity, the lower end of kapitbahay camera is on the same level with the lower end of the hydrocyclone apparatus, exhaust pipe line the bottom end set at the level corresponding to the upper generatrix of technological capacity, and gas equalizing pipe one end of which is placed in the gas cavity technological capacity, and the other is in the axial zone of the gas exhaust pipe, in addition, between gas equalizing pipe and the maximum liquid level horizontal technological capacity placed bumpers to prevent brythons in the exhaust pipe line.
