Abstract

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.
