EQUIPMENT FOR GAS CLEANING OUT OF HYDROGEN SULFIDE Russian patent published in 2009 - IPC B01D53/52 B01J10/00 

FIELD: oil-and-gas production.

SUBSTANCE: invention can be used for reservoir hydrogen sulfide neutralisation systems, rubbish places, pit gases and biogas production plants, when refined gas is under pressure approximately equal to atmospheric one. Equipment contains tank with absorber 1, gas cleaning with absorber equipment, pumps for absorber circulation 9, 10, air compressor 11, sulphur extraction device 12 and control device 14. The tank with absorber 1 limited with hermetic case with exhausted air nozzle 2 and includes device for absorber regeneration 3, formed with air distributor 3' and walls 4 and 5. The wall 4 stiffly connected to the tank 1 case top part, and the wall 5 executed with gap relatively to the tank 1 case. The gas cleaning with absorber equipment includes two liquid jet injector pumps 6, two columns for gas cleaning 7, equipped with injection nozzles 8 and mist separators 18. The column for gas cleaning 7 bottom part located inside the tank with absorber 1, at that columns for gas cleaning 7 end part executed vertically up bended and connected under air distributor 3'.

EFFECT: gas cleaning efficiency increase, equipment dimensions reduction, production and installation casts cutting, power consumption and maintenance casts cutting.
