Process for the removal of CO¶2¶ and sulfur compounds from technical gases, in particular from natural gas and raw synthesis gas

摘要

An absorbent made of N-formylmorpholin (NFM) and N-acetylmorpholin (NAM) is used at -20 to +40o C in the absorber for removing CO2 and sulfur compounds from technical gases, especially natural gas and crude synthesis gas. Process for removing CO2 and sulfur compounds from technical gases, especially natural gas and crude synthesis gas, comprises liberating the gas to be purified from acid gas components in an absorber at a pressure of 10-150 bar by absorbing with an absorbent made of N-formylmorpholin (NFM) and N-acetylmorpholin (NAM), and regenerating the absorbent charged with the acid gas components and recycled to the absorber.
