FIELD: gas industry.
SUBSTANCE: method of gas-dynamic separation relates to low-temperature processing of multicomponent hydrocarbon natural and casinghead gases, in particular, for gas drying by condensation and separation of water and/or hydrocarbon components, and can be used in systems for collecting, preparation and processing of multicomponent hydrocarbon gases. Method of gas-dynamic separation comprises supplying the flow of high pressure multicomponent hydrocarbon gas into the nozzle, its isoenthalpic expansion and cooling while flowing in the nozzle, condensation of components in the cooled gas flow, separation of condensate from gas phase and increasing pressure by braking in the diffuser. Separated hydrocarbon condensate in contact with the initial gas is being partially evaporated and additionally cooled, and the initial gas is being cooled while heat exchange with a coolant additionally cooled by the condensate.
EFFECT: technical result is high efficiency of gas-dynamic separation and reduced power consumption.
