EJECTOR, DEVICE AND PROCEDURE FOR PREPARING GASEOUS MIXTURE OF LIGHT HYDROCARBONS TO PROCESSING Russian patent published in 2011 - IPC C10G5/00 C10G5/06 

FIELD: oil and gas production.

SUBSTANCE: here is disclosed ejector consisting of nozzle unit, nozzle, primary mixing chamber, secondary mixing chamber, diffuser, receiving chamber, gas inlet, and fluid inlet. Also, the primary mixing chamber corresponds to a conic shape case wherein there are arranged toroid circular elements with a gap relative to each other. Further, there is disclosed the device for preparing gaseous mixture of light hydrocarbons. The device contains a separator, a fluid outlet of which is coupled with a fluid inlet of the ejector consisting of the nozzle unit, the nozzle, the primary mixing chamber, the secondary mixing chamber, the diffuser, and the receiving chamber. Additionally, the primary mixing chamber is made in form of a conic shape case wherein there are arranged toroid circular elements with a gap relative to each other. The gas inlet of the ejector is connected to a source of processed gaseous mixture of hydrocarbons. The outlet of the said ejector is coupled with the inlet of the separator. The gas outlet of the separator is connected with the first inlet of a mixture-absorber, the second inlet of which is connected to a source of organic liquid, while the outlet transfers treated gaseous mixture of hydrocarbons to processing. There is disclosed the procedure for processing gaseous mixture of light hydrocarbons. The procedure consists in compressing gaseous mixture, and in producing a liquid phase containing mixture components. Gaseous mixture of light hydrocarbons is compressed and liquid phase is produced with the above described ejector. Components of the liquid phase are condensed and absorbed with active flow of water or water-organic medium.

EFFECT: raised efficiency of processing mixture of light hydrocarbons.
