METHOD OF PREPARATION OF HYDROCARBON GAS FOR TRANSPORT Russian patent published in 2015 - IPC B01D19/00 

FIELD: oil and gas industry.

SUBSTANCE: formation gas is supplied to the separator of the first stage. The gas separated in the separator of the first stage is compressed and cooled. The compressed and cooled gas is fed through the heat exchanger of the first cooling stage to the separator of the second stage. The gas separated in the separator of the second stage is fed through the heat exchanger of the second stage of cooling and the reducing device in the separator of the third stage. The liquid is fed from the separator of the second stage in the pipeline between the reducing device and the separator of the third stage. The liquid is removed from the separators of the first and the third stage for further preparing. The gas is fed from the separator of the third stage to the heat exchanger of the second stage of cooling. The gas is fed from the heat exchanger of the second stage of cooling to the reducing device. The gas is fed from the reducing device to the heat exchanger of the first stage of cooling and then this gas is removed from the unit.

EFFECT: increase in the yield of unstable condensate at the units of three-stage low-temperature separation of gas with booster compressor station and two-stage gas throttling.
