IMPROVED METHOD FOR REGENERATION OF ABSORBENT |
摘要 |
<p>A method for regeneration of a rich absorbent having absorbed CO2, to give a regenerated, or lean absorbent, and CO2, is described. The rich absorbent is brought in countercurrent flow with steam at least partly generated by heating lean absorbent in a reboiler at the base of the regeneration column, where released CO2 and steam are withdrawn from the top of the column. Lean, or re-generated absorbent is withdrawn from the base of the column, and is flashed over a flash valve and separated in a flash tank into a gas phase, that is compressed and returned into the regenerator column, and a liquid phase mainly comprising lean absorbent that is cooled by heat exchanging against incoming rich absorbent, wherein the gas phase and/or the lean absorbent is/are heat exchanged against a low temperature heat medium after leaving the flash valve.</p> |
