PLANT FOR REAGENTLESS DEHYDRATION OF GAS (VERSIONS) Russian patent published in 2000 - IPC

FIELD: oil and gas industries; gas wells; gas fractionating plants of petrochemical complexes. SUBSTANCE: proposed plant includes separator for primary gas cleaning, separators for main first- and second-stage cleaning, separators for main first - and second-stage cleaning arranged in common housing with heat exchanger, gas flow rate, pressure and temperature measuring units, liquid receiver connected with cavities of separator and made in form of vortex chamber and separator in one housing. Proposed plant provides for effective cleaning of gas from drops of liquid and solid particles in inlet separator, separation of gas in vortex separator into cold and hot flows; water and hydrocarbons at molecular mass above methane are concentrated in hot flow. Dropping liquid is separated from hot flow and hot flow gas is directed to second stage of vortex chamber where gas is separated into cold and hot flows at concentration of water heavy hydrocarbons in hot water. Hot flow is cooled by cold flow of vortex separator in heat exchanger-separator entrapping liquid drops. Cold flows of vortex separator, vortex chamber and end separator are mixed and fed to consumer. Dividing of gas flow in vortex separator and vortex chamber is effected at fraction of cold of 0.8. EFFECT: enhanced efficiency. 3 cl, 2 dwg
