<p>A liquid and a carbon dioxide containing gas are brought into intimate contact with each other while flowing countercurrently through a column divided into three contact zones. The liquid flows through the first contact zone at a relatively low temperature t1 to take up carbon dioxide from the gas, then through the second contact zone for delivering carbon dioxide and oxygen to said gas at a higher temperature t2, and finally through the third contact zone to take up carbon dioxide at a lower temperature t3 with respect to the temperature t2.</p> |
