摘要 |
The invention relates to a desulfurization process, wherein a gas mixture is subjected to a separation process to separate the acidic components of the gas, an acid gas containing carbon dioxide and sulfur compounds, in particular hydrogen sulfide, being formed in this process, the acid gas being sent to a Claus plant for separation of elemental sulfur, and the residual gas leaving the Claus plant being subjected to a further separation, in which the water formed in the Claus process is at least partially removed, only technically pure oxygen being supplied as the oxygen-containing reaction gas to the Claus plant, and carbon dioxide in a purity which allows direct sequestration or industrial utilization being removed downstream from the Claus plant. |
