ABSORBENT FOR REMOVING HS AND COFROM GASES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to removing hydrogen sulphide and carbon dioxide from gases. The absorbent contains methyl diethanolamine, a fraction of vacuum distillation of technical polyethylene polyamine with boiling range of 50-200°C, a water-soluble physical solvent and water. The water-soluble physical solvent used is polyethylene glycol or methyl ethers of polyethylene glycol of formula CH-O(CHCHO)-H, where x=2-5.EFFECT: invention provides high efficiency of removing HS and COfrom gases while maintaining high efficiency of regenerating the absorbent from acidic components.3 cl, 3 tbl
