Abstract

This invention relates to gas pipeline transport, primarily from gas condensate fields. The purpose of the invention is the complete utilization of condensate due to its fine dispersion in a gas stream. For this, the gas pipeline with a condensate collector is equipped with an ejector connected with an inlet and an outlet with a gas pipeline before and after the diaphragm, respectively. In this case, the receiving chamber of the ejector is connected to a condensate collector, 2 Il.

This invention relates to pipeline transport of gas, mainly from a gas condensate field.

The aim of the invention is the complete utilization of condensate due to its fine dispersion in a gas flow.

This is achieved by supplying an ejector device connected to the gas inlet and outlet before and after the tapering device, respectively, and connecting the ejector receiving chamber with the condensate collector.

Supplying the gas pipeline with an ejector connected to the gas inlet and outlet before and after the narrowing device, respectively, allows to create a pressure differential before and after the narrowing device, to direct part of the gas flow through the ejector and create a vacuum in its receiving chamber,

The connection of the receiving chamber of the ejector with the condensate trap allows, due to the vacuum in the receiving chamber, to direct the condensate from the condensate collector to the elevated section of the pipeline and transport it in the gas flow. The ejector produces a primary gas atomization in the stream.

FIG. 1 depicts the proposed device; in fig. 2 schematically shows the installation of the ejector.

The device includes a gas pipeline 1, a condensate trap 2, a diaphragm 3, an ejector 4, an inlet 5 and an outlet 6 of the ejector and a connecting pipe 1 ..

The device works as follows.

In the process of gas transfer, the condensate constantly accumulates in the condensate of the collector 2. PASSING the diaphragm 3 at a speed of 0.5-50 m / s

the pressure zone in front of the diaphragm 3 and the pressure zone behind it. The overpressure zone is connected to the inlet 5 of the ejector 4, and the underpressure zone to the outlet 6 of the ejector 4. As a result of the pressure difference between inlet 5 and outlet 6 in the ejector 4, the gas moves from inlet 5 to outlet 6 and in the receiving chamber of the ejector 4 vacuum is created, therefore condensate from condensate collector 2 through pipeline 7 will be drained into the receiving chamber 5 of ejector 4, mixed with gas and discharged as outlet 6 into the gas stream moving through gas pipeline 1. Condensate flows into the receiving chamber 4 py ejector perpendicular to the movement of gas. Formed from the aerosol enters the gas pipeline, where it is again crushed perpendicular to the gas flow moving along the gas pipeline.

At gas velocities of 0.5–50 m / s and pressures up to 7.0 MPa, an appropriate diameter of the tapering device is selected by calculation, at which the required differential pressure can be achieved.
