UNIT FOR PUMPING AND COOLING ASSOCIATED PETROLEUM GAS, DEVICE AND METHOD FOR FLUSHING IT Russian patent published in 2021 - IPC F04D29/00 

FIELD: petroleum gas pumping.

SUBSTANCE: invention relates to the field of pumping associated petroleum gas, namely to flushing the interchangeable flow part of a centrifugal compressor (CC) and the in-line space of air gas coolers (AGC). The unit for pumping and cooling of associated petroleum gas includes a first section of a gas pipeline connected to a centrifugal compressor, a second section of a gas pipeline connecting a centrifugal compressor and a gas air cooler, which is connected to a third section of a gas pipeline, while in the in-pipe space of the first and/or second section of a gas pipeline a washing device with the possibility of supplying a cleaning solution inside the gas pipeline into the flow of a gaseous medium with its subsequent transfer into the cavity of a centrifugal compressor and/or the in-tube space of an air gas cooling apparatus, respectively.

EFFECT: simplification of the design of the unit for pumping and cooling of associated petroleum gas, increasing the reliability of its operation, ensuring better flushing of the unit with a reduced consumption of solutions.
