SU971404A1 - Device for separating oil, water and gas - Google Patents

Description

The invention relates to devices for the separation of oil, water and gas and can be used in the oil and gas industry in oil and gas treatment systems, as well as in well testing facilities.

Closest to the proposed device for the separation of oil, water and gas, comprising a vertical body with a lid, in which conical plates are installed in height, a vertical cylinder placed outside the plates, and water collection tubes attached to their base Cl.

The disadvantage of this device is the low efficiency of the water separation process caused by the opposite direction of movement of the main fluid flow and the settling water droplets. In addition, in the presence of a gas phase due to the large thickness of the liquid layer is difficult to release gas bubbles.

The aim of the invention is to intensify the process of separating oil, water and gas and to improve the quality of separation.

This goal is achieved by the 1 WHT device to separate

water and gas, comprising a housing, a lid, a vertical cylinder with conical plates and drain pipes, is equipped with a filling pipe, and the drain pipes are divided into sectors by partition walls and are equipped with canopies located above the water drainage hole, and conical plates are attached to the body with the formation of 3 compartments .

It is advisable to divide the loading pipe with bridges into channels according to the number of plates.

FIG. 1 isobreiken general view of the device; in fig. 2 - section A-A of FIG. one; in fig. 3 - node I of FIG. 1 in FIG. 4 - section bb FIG. 3; FIG. 5 is a section along the line BB of FIG. 3

The device contains a cylindrical body 1, an inlet 2, conical plates 3 attached to the body, a filling pipe 4, drain pipes 5 with canopies 6, a float chamber 7 in which 25 float valve 8 is located, drop-catch & output pipes of oil, gas, water 10, 11, 12, respectively, and drainage pipes 13, 14.

Claims (2)

The device works in the following 30 ways. The gas-liquid flow of the production of the well goes through the inlet pipe 2. Under the action of gravitational forces, the liquid is drained to the upper plate 3 and through the drain hole fills the central channel with the pipe 4, the drain pipe 14 and the float chamber 7 At the same time the float valve 8 closes the bottom side holes pipe 4 channels so that the liquid does not flow from the upper plates to the lower ones. Then the liquid from the central channel of the filling pipe 4 is poured IB side channels and through the holes in Them enters the plates 3, filled them to a level defined by the location of holes du1 water and oil drain tubes, the liquid flow through the compartments Re.spredelenie relatively thin layer provides a larger surface 5zozmozhnost receive interface and 1azoobraznoy liquid phase. When this occurs, an intensive release of puzzles of gas occurs, and the separation of fluid into oil and water. Water droplets, due to the greater nickname, are deposited on the surface of the plate, forming a layer of water, which, as it increases, fills the space under the visor to the level of the opening E of the drain tube 5, after which the water flows to the lower part of the device and leaves through a branch pipe 12. Oil is also discharged in a separate channel of the drain pipe 5 through the hole located at the bottom of the device and discharged through the pipe 10. Dedicated gas through the corresponding drain pipes. blunt to the upper part of the device, where a drip catcher section is installed for additional separation, the separated gas is discharged through pipe 11. For drainage drainage is provided;: pipes 13 and 14. The advantages of the device compared to the base one are to intensify the separation process of oil, gas and water, caused by the distribution of fluid flow relatively thin layer on a large surface. In addition, this structure has a good drain and is easy to clean. This device is planned to be used in the development of offshore fields, and the vertical use of the device significantly saves space on the offshore platform, which is quite significant. Claim 1. A device for separating oil, water and gas, comprising a housing, a vertical cylinder with conical plates and drain pipes, with an opening for draining water, characterized in that, in order to intensify the separation process and improve the quality of separation, the device is provided with a bulk the pipe, the drain pipes are divided into sectors by partitions and are equipped with visors located above the water drain, and conical plates are attached to the body; d the formation of closed compartments. 2. The device POP.1, characterized in that the filling pipe is divided by jumpers into channels, the number of which corresponds to the number of plates.
