PLANT FOR CLEANING GAS FROM HYDROGEN SULFIDE Russian patent published in 1994 - IPC

FIELD: oil industry. SUBSTANCE: plant has an absorber, a regenerator, rounded pipelines positioned crosswise which interconnect the absorber and the regenerator so as to connect their upper parts to lower ones respectively. The pipeline sections entering the lower part are mounted tangentially to the bodies of the absorber and the regenerator and are located below gas and air distributors. The inlet sections of upper parts of the pipelines have inclined connecting members with diameters reducing from top to the bottom which are connected to pockets located on the inner walls of the bodies. The lower parts of the absorber and the regenerator are also connected to each other and to a sulfide release unit by pipelines. The pipeline for bringing the absorber from the sulfide release unit is tangentially connected to the lower parts of the absorber and the regenerator. Their inlets are located below the gas and air distributors oppositely to inlet sections of the crosswise pipelines. The upper part of the regenerator has an air control valve connected to a pressure pickup mounted in the upper part of the absorber. The plant also has an inlet separator, an outlet separator, a pump, a compressor, feed and bleed pipelines. EFFECT: reduced material costs. 1 dwg, 1 tbl
