METHOD FOR STABILIZATION OF GAS CONDENSATE Russian patent published in 2016 - 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. Reflux section as a cooling agent is fed with reduced unstable condensate, which then is directed to the feed zone, from the top of the reflux section hydrocarbon gas is discharged, and from the bottom of the stripping section the condensate is discharged, which is divided into two parts: one part of the condensate is heated and separated to form a separation gas, which is directed to the bottom of the stripping section as a stripping agent, and a separation residue, which is mixed with the other part of the condensate, fed as a heat carrier into the stripping section and discharged as a commercial condensate. Hydrocarbon gas is compressed, cooled and separated under the conditions of dephlegmation and stabilization of the reflux to produce a propane-butane fraction and a weathering gas.

EFFECT: technical result is increased output and wider range of commercial products, reduced volume of weathering gas, reduced power inputs.
