METHOD FOR CONDITIONING OF HYDROGEN SULPHIDE- AND MERCAPTAN-CONTAINING ASSOCIATED PETROLEUM GAS Russian patent published in 2015 - IPC B01D53/00 

FIELD: oil and gas industry.

SUBSTANCE: method is suggested wherein associated petroleum gas is mixed up with gas containing vapours of heavy hydrocarbons and mercaptans, separated with obtainment of condensate directed to the stage of oil refinement and compressed. Besides gas is purified from hydrogen sulphide with obtainment of acid gas or sulphur, from heavy hydrocarbons and mercaptans with obtainment of gas containing vapours of heavy hydrocarbons and mercaptans and subjected to mild reforming process together with water and flow containing water. The received catalyzate is dried with obtainment of flow containing water and conditioned gas. When required catalyzate is purified additionally from impurities, which concentrate and at least a part of gas containing heavy hydrocarbons and mercaptans is used for auxiliaries.

EFFECT: increase in volume yield and improved quality of conditioned gas as well as exclusion of waste generation.
