Abstract: The present invention relates to a gas purification system for removal of acidic gases from a gas stream. The system comprises an absorption unit arranged for receiving a gas stream and contacting it with a wash solution stream and a cooling unit in fluid communication with the absorption unit. The cooling unit receives wash solution enriched with acidic gases from a first withdrawal level of said absorption unit, cools the enriched wash solution, and provides cooled, enriched wash solution to a first reintroduction level of the absorption unit upstream of the withdrawal level. The ratio of withdrawn wash solution is 10-90% of the total wash solution stream.

Abstract: The present disclosure describes the efficient use of a catalyst, an enzyme for example, to provide suitable real cyclic capacity to a solvent otherwise limited by its ability to absorb and maintain a high concentration of CO2 captured from flue gas. This invention can apply to non-promoted as well as promoted solvents and to solvents with a broad range of enthalpy of reaction.
