METHOD FOR STABILIZATION OF GAS CONDENSATE Russian patent published in 2017 - IPC B01D3/14 C07C7/04 

FIELD: gas industry.

SUBSTANCE: invention relates to methods of preparing gas condensate for single-phase transfer and can be used in gas industry. Method for stabilization of gas condensate comprises separation of reduced unstable condensate, which is carried out in one stage in a film column, consisting of a cooled reflux and a heated stripping sections and a feed zone, located between them. As cooling medium reflux section is supplied with reduced unstable condensate, and then it is directed into supply zone. From reflux section top hydrocarbon gas is discharged, and from stripping section bottom condensate is discharged, which is divided into two parts. One part of condensate is heated and separated with formation of separation gas, which is directed to the bottom of the stripping section as a stripping agent, and a separation residue, which is mixed with another part of condensate, supplied as heat carrier into stripping section and discharged as commercial condensate. Hydrocarbon gas is compressed, cooled down and separated under dephlegmation conditions and reflux stabilization to produce propane-butane fraction and gas weathering.

EFFECT: technical result is increased output and wider range of commercial products, reducing amount of weathering gas and power saving.
