<p>and/or H2S is removed from gas mixtures by washing with aq. alkaline soln. which can later be regenerated. Process comprises washing under pressure, removing streams, which are then regenerated, are in a high pressure zone, the other in a low pressure zone. When the pressure in the high pressure zone is produced, the mixture cools to produce steam, which is then used to strip the low pressure zone. Finally, both regenerated streams are returned to the absorbing zone.</p> |
