Absorbent composition and process for removing CO2 and/or H2S from a gas comprising CO2 and /or H2S

摘要

An absorbent composition for removing CO and/or HS from a gas comprising a polyamine, a monoamine and water, wherein the polyamine comprises a polyamine having 3 to 5 amine functions and has a molecular weight of less than 200 g/mol; wherein the monoamine comprises a tertiary monoamine; and wherein the weight ratio of the polyamine having 3 to 5 amine functions to the tertiary monoamine is more than 1:1. A process wherein such an absorbent composition is used and a use of a tertiary monoamine as an accelerator for accelerating the removal of CO and/or HS from a CO and/or HS containing polyamine having 3 to 5 amine functions.
