FIELD: oil and gas industry.
SUBSTANCE: invention is related to gas treatment methods and may be used in the oil and gas industry, oil processing and petrochemical industry at the amine treatment of hydrocarbon gases from acid components. The invention suggests a method for the treatment of industrial and refinery gases that includes the compression of the treated gas by a liquid-ring compressor using a mixture of an aqueous solution of alkanolamine and a hydrocarbon fraction with the mass ratio of components of 0.1-10:1 as the working liquid and further separation of the compressed gas with the production of the treated gas, Y-grade NGLs sent to further processing and the saturated aqueous solution of alkanolamine sent for regeneration.
EFFECT: invention allows preventing the pollution of a saturated absorbent by heavy hydrocarbons and mercaptans, reducing losses of hydrocarbons C4+ and energy costs.
