Abstract:
    The invention relates to a process for removing CO2 and sulfur compounds from technical gases, especially natural gas and crude synthesis gas, comprising liberating the gas to be purified from acid gas components in an absorber at a pressure of 10-150 bar by absorbing with an derivative of morpholin, and regenerating the absorbent charged with the acid gas components and recycled to the absorber. N-formylmorpholin (NFM) and N-acetylmorpholin (NAM) mixtures are used as the absorbent at temperatures between -20 DEG C. and 40 DEG C in the absorber.
