PROCESS FOR THE REMOVAL OF CO2 AND SULFUR COMPOUNDS FROM INDUSTRIAL GASES, IN PARTICULAR FROM NATURAL GAS AND RAW SYNTHESIS GAS

摘要

A process for the removal of CO2 and sulfur compoundsfrom natural gas and raw synthesis gas wherein N-formylmorpholineand N-acetylmorpholine mixtures are used as the desorbent attemperatures between -20°C and +40°C at pressures of 10 to 150bar in a scrubbing operation. The acid gases are removed fromthe absorbent by flashing and the regenerated absorbent isrecycled to the absorbent.
