METHOD AND APPARATUS FOR CLEANING GASES FROM GAS CONDENSATE Russian patent published in 1999 - IPC

FIELD: gas separation. SUBSTANCE: method involves absorbing gas with liquid absorbent, such as gas condensate; throttling inflow gas; injecting gas condensate into negative pressure zone and enriching gas flow. Prior to dividing liquid absorbent flow into two flows, liquid absorbent is preliminarily swirled and repeatedly swirled in swirling pipe and simultaneously condensed, with supersaturation of predetermined value being maintained in swirling pipe. Method further involves supplying liquid absorbent as gas condensate for absorption. Apparatus has shell with swirling pipe concentrically positioned within shell so as to define annular space between them. Shell has hot and cool flow chambers and energy separator having inlet tangential nozzles positioned in swirling pipe and disk with through channel, which provides communication between hot and cool flow chambers. Outlet tangential nozzles are positioned at other end of swirling pipe for communicating hot flow chamber with annular space. This end of swirling pipe is closed with ejector. Outer surface of swirling pipe is provided with fins. Condensate outlet is positioned in energy separator disk. EFFECT: increased efficiency and intensified removal of gas condensate from gas, reduced metal usage and reduced power consumption. 3 cl, 1 dwg, 1 tbl
