ABSTRACT:
The process for the purification of liquids and in particular the regeneration of spent absorbent solutions is essentially based on the use of a first preliminary regeneration zone to which the entire solution to be purified is delivered and the use of two terminal regeneration zones operating respectively at a higher and a lower pressure. The semi-regenerated solution issuing from the preliminary purification zone is split into two fractions which are delivered respectively to the low pressure and the high pressure terminal zones. The fraction delivered to the high pressure terminal zone is regenerated by steam yielded by means of the supply of external heat to the bottom of the zone. The fraction delivered to the low pressure terminal zone is regenerated by steam produced by heat recovered from the high pressure terminal zone.
