Process for removing undesirable components from gases

In a process for regenerating a scrubbing medium which has been utilized in a scrubbing operation, said scrubbing operation comprising contacting a gaseous mixture with a scrubbing medium to obtain a scrubbed gas fraction and said scrubbing medium loaded with scrubbed-out components from said gaseous mixture, and said process for regenerating comprising expanding the loaded scrubbing medium to release scrubbed-out components therefrom, the improvement comprising:

• expanding said loaded scrubbing medium in a first stage and at least one downstream expansion stage to obtain resultant regenerated scrubbing medium, wherein said loaded scrubbing medium is expanded in said first stage through a liquid-jet compressor to form resultant expanded loaded scrubbing medium and first stage expansion gases, and
• further expanding the resultant expanded loaded scrubbing medium in one of said at least one downstream expansion stage to form further expanded scrubbing medium and downstream expansion gases, separating said downstream expansion gases from said further expanded scrubbing medium, and passing said downstream expansion gases into said liquid-jet compressor.
