A method. and plant for regeneration of a rich absorbent having absorbed C02, to give a regenerated, or lean absorbent, and C02, where the rich absorbent is regenerated by stripping against steam in a regenerating column (8), where gas, mainly comprising released C02 and steam, is withdrawn from the top of the column (9) and separated (25) to give a stream of C02 that is removed, and condensed water (27) that is recycled into the regenerator column, and where lean, or regenerated, absorbent is withdrawn from the base of the column (4), wherein the gas that is withdrawn from the top of the regenerator column (9) is compressed (21) and cooled by heat exchanging to recover the heat (23,24), before separation of the gas into C02 and water. |
