PROCESSO DE SEPARACAO SELETIVA DE HIDROGENIO SULFURADO DE MISTURAS GASOSAS CONTENDO TAMBEM ANIDRIDO CARBONICO

摘要

There is disclosed a process for selectively separating hydrogen sulfide from gaseous mixtures which also contain carbon dioxide by chemical absorption with a substantially anhydrous solution of a tertiary amine, such as methyl diethanolamine, and an auxiliary organic solvent, such as sulfolane.
