METHOD FOR EXTRACTING WET GASES FROM HYDROCARBON GAS MIXTURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC B01D53/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used to extract wet gases from a mixture of hydrocarbon gases. Device contains at least an inkjet apparatus for compressing a mixture of hydrocarbon gases, a stabilization column and an absorption unit. Absorption unit includes separator and absorber. Bottom of the absorber is connected to the top of the separator, in which the saturated hydrocarbon fraction is separated by gravity after absorption. Absorber is equipped with refrigerant input and output lines. Made with the possibility of absorption of predominantly wet gas from a mixture of hydrocarbon gases. In the stabilization column, stabilization gas, liquefied wet gases, a stable hydrocarbon fraction are obtained, and part or all of the stable hydrocarbon fraction is supplied to the absorber as an absorbent. Working medium is also circulated around the circuit, and stabilization gas is used as the working medium of the jet apparatus.

EFFECT: invention provides an increase in the efficiency of heat exchange, an increase in the degree of wet gases extraction in the stabilization column, and a reduction in capital costs.
