GAS-DYNAMIC SEPARATOR Russian patent published in 2009 - IPC B01D45/12 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to equipment for low temperature gas processing, for example, multi-component natural and oil hydrocarbon gases and can be implemented for low temperature preparing, processing, dewatering, stripping multi-component hydrocarbon gases. The separator consists of a case, of a branch for input of source multi-component hydrocarbon gas, of a gas vortex, of a branch of fluid input into a flow of gas, of a Laval nozzle for isoenthalpic expanding and cooling of a swirled gas flow, of a separating chamber for separation of condensed components from expanded and cooled rotating flow of gas, of a film stripper of condensate, of a condensate collector, of an ejector of withdrawal of gaseous phase from the condensate collector, of a diffuser for increasing pressure of a scrubbed gas flow and of an installed in the case transverse partition, which divides the internal space of the case into two cavities. The first cavity is connected with the branch of input of source gas, with input to the vortex and with condensate collector. In this cavity, coaxially with the case, there are successfully arranged the vortex, the Laval nozzle and the separating chamber. The second cavity is connected to the condensate film stripper from the separating chamber, to the ejector and to an additional condensate collector.

EFFECT: increased efficiency of gas-dynamic separation and reduced power consumption.
