Abstract
To regenerate a physical solvent, loaded with sour gases, especially CO.sub.2 and H.sub.2 S, the loaded solvent is treated with a stripping gas and/or is expanded to separate absorbed CO.sub.2 and the resultant solvent is subjected to thermal regeneration to desorb H.sub.2 S. To reduce energy requirements during regeneration, the CO.sub.2 desorption is conducted on at least two different temperature levels, the second being for example 30.degree.-80.degree. C. higher than the first, with the first being conducted, e.g., at about those low temperatures conventional to low temperature absorption systems.
