| titleOfInvention | Composition and method for removal of carbonyl sulfide from acid gas containing same |
| abstract | Novel solvent composition for selective removal of COS from a gas stream containing same, said composition comprising a) at least one polyalkylene glycol alkyl ether of the formula R1O-(Alk-O)n—R2 (I) or 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone or a mixture of N-formylmorpholine and N-acetylmorpholine wherein R1 is an alkyl group having from 1 to 6 carbon atoms; R2 is hydrogen or an alkyl group having from 1 to 4 carbon atoms; Alk is an alkylene group, branched or unbranched, having from 2 to 4 carbon atoms, and n is from 1 to 10; and b) at least one alkanolamine compound of the formula R3NHR4OR6 (II) or at least one piperazine compound of formula wherein R3 is hydrogen, an alkyl group having from 1 to 6 carbon atoms, or the R4OH group; R4 is a branched or unbranched alkylene group having from 1 to 6 carbon atoms; R5, independently in each occurrence, is hydrogen or an hydroxyalkyl group having from 1 to 4 carbon atoms; and R6 is hydrogen, an alkyl group having from 1 to 6 carbon atoms or an hydroxyalkyl group having from 1 to 4 carbon atoms. |
