FIELD: oil and gas industry.
SUBSTANCE: invention relates to devices for cooling and separation of multicomponent compressed gases, in particular associated petroleum gas, and can be used in oil and gas industry. Disclosed is a fractionating absorber, including absorption section equipped with unit of mass-exchange elements equipped with nozzles of input/output of the coolant, zone of supply with associated oil gas feed branch pipe, upper separation zone with inlet branch pipes of stable oil and clean gas discharge and lower separation zone with unstable oil discharge branch pipe. During operation of the absorber compressate is delivered to the supply zone, in upper separation zone stable oil is fed, which in countercurrent contact with hot kompressatom under conditions of temperature gradient is created due to cooling by coolant, absorbs gas hydrocarbons C4+ and partially stabilises. Purified gas is removed from the top of the separation zone, and unstable oil is removed from the bottom of the separation zone.
EFFECT: technical result is simplification of the fractionating absorber and reducing power consumption.
