| description | The present invention relates to a process and plant for removing acid gases such as carbon dioxide, sulphur containing compounds and nitrogen containing compounds from gas streams including high and low pressure gas streams. A solvent solution containing alkali carbonates absorbs the acid gases including carbon dioxide and either one or both of sulphur and/or nitrogen containing compounds. The bicarbonate is regenerated into a carbonate form to provide a gas stream rich in carbon dioxide, and sulphur and/or nitrogen containing compounds are recovered.
La présente invention porte sur un procédé et une installation pour l'élimination de gaz acides tels que le dioxyde de carbone, des composés contenant du soufre et des composés contenant de l'azote de courants de gaz dont des courants de gaz à haute pression et à basse pression. Une solution de solvant contenant des carbonates alcalins absorbe les gaz acides dont le dioxyde de carbone et des composés contenant du soufre et/ou des composés contenant de l'azote. Le bicarbonate est régénéré en une forme de carbonate pour produire un courant de gaz riche en dioxyde de carbone et les composés contenant du soufre et/ou de l'azote sont récupérés. |
