Description

(54) DEVICE FOR COLLECTION (AND CONDENSATE TRANSPORTATION

-:.one

This invention relates to pipeline gas transportation, primarily from gas condensate fields.

A device for collecting and transporting condensate on gas pipelines is known, which includes a condensate collector installed at a lower point of the gas pipeline and equipped with a spray nozzle inserted into the gas pipeline 1.

The disadvantage of this device is that it does not provide the necessary zhezatsii, condensate from the condensate collector to the gas pipeline. In addition, the placement of spray nozzles in the cavity of the pipeline violates its normal hydraulic mode and eliminates the possibility of the cleaning pistons passing through the pipeline.

The closest technical solution to the invention is a device for collecting and removing condensate on gas pipelines, including a condensate collector installed at a low point of the pipeline, equipped with a float level regulator and a valve for discharging the assembled GAS PIPELINE

condensation tank condensate tanker 2.

A disadvantage of the known device is the complexity of its operational service, which is inflated by the large length of trunk gas pipelines and the location of its low points, as a rule, in hard-to-reach places. This reduces the effectiveness of the device.

The aim of the invention is to increase the efficiency of the device.

This goal is achieved by inserting a buffer tank into the device, connected to the gas pipeline, condensate trap and atmosphere and equipped with valves controlled by a condensate level regulator.

In order to prevent the loss of propane and condensate emissions when filling the buffer tank, a safety valve is installed on the exhaust plug, which is adjusted to release gas at a pressure of 1617 MPa. 3 The drawing shows the proposed device. The device includes a condensate collector 2 installed at a low point of the gas discharge pipe 1 with a shut-off valve 3 controlled by a condensate level regulator 4. The condensate collector is connected via pipeline 5 to a buffer tank 6, equipped with a level regulator 7, a drain 8 and a three-way valve 9 and a discharge candle 10 on which “a safety valve 11 is installed. a three-way valve 9 is in communication with a gas pipeline 1. The device operates as follows. In the initial position, valves 3 and 8 are closed, and a three-way valve 9 is open to a candle. During this position of the valves, the cavity of the condensate trap is connected to the gas pipeline, and the cavity of the buffer tank 6 is connected to the pipeline 5 and through the three-way valve 9 to the safety valve 11. During gas transfer, the condensate periodically accumulates in the condensate collector 2. When the condensate collector is filled, the condensate level controller 4 signals f. the valve 3 is opened, and the condensate under pressure of gas (60-70 MPa) is moved to the buffer tank 6. When the pressure in the buffer tank exceeds 16-17 MPa, the safety valve opens, and the buffer tank 6 through the candle 10 communicates with the atmosphere, which makes filling it out. After the condensate collector 2 is released from the condensate, the valve 3 closes by a signal from the condensate level regulator 4. When the level of condensate in the buffer tank 6 reaches the upper control point, the signal of the regulator 7 of level 7 opens the valve 8 and the three-way valve switches the upper part of the tank through jumper 12 with the gas pipeline I, thereby equalizing the pressure in the lower and upper part of the buffer tank. As a result, condensate from the buffer tank is transferred to the gas pipeline and transported in the gas flow to the next similar device (along the gas pipeline route there may be several, depending on the length of the gas pipeline and the terrain relief). Techno-economic effect of the invention is expressed in providing automated collection and transport of condensate through the pipeline without disrupting its normal operation. Claims An apparatus for collecting and transporting condensate on gas pipelines, including a condensate trap with a level control and a condensate discharge valve, is so that, in order to increase the efficiency of its operation, a buffer tank is introduced into it. It is connected to a gas pipeline, a condensate trap and the atmosphere and is equipped with valves controlled by a condensate level regulator.
