INSTALLATION FOR CATCHING HYDROGEN SULFIDE-CONTAINING VAPORS Russian patent published in 1997 - IPC

Abstract RU 2077931 C1

FIELD: oil and gas industry. SUBSTANCE: invention relates to installations for catching and purifying hydrogen sulfide-containing gases and can be employed when neutralizing hydrogen sulfide in outbursts of storage tank gas under condition of oscillating mode of filling tank with liquid (water-oil emulsion). Invention is aimed at reducing power consumption on gas compression and increasing reliability under aforementioned condition. Installation has: tanks, compressor, separator-absorber, input (low-lift) gas line connecting tanks to compressor, output (forcing) gas line connecting compressor to separator-absorber, additional separator containing vertical pipe unit, gas line with pressure control connecting lower part of separator to low-lift gas line, gas line connecting lower part of pipe unit to forcing gas line, gates, sulfur removal branch pipes, and entrainment separator arrangements. EFFECT: improved installation process flowsheet and reduced cost. 1 dwg, 1 tbl
