ABSTRACT:
In a process for the regeneration of a loaded scrubbing medium in a regenerating column which is equipped with a bottoms heater and a heat condenser, the process involving stripping the loaded scrubbing medium with a vapor, wherein after condensation of the vapor in the head condenser the stripped-out components are removed and the remaining condensate is reintroduced to the regenerating column, the improvement comprising that the condensate, prior to being reintroduced to the regenerating column, is at least partially revaporized in a vaporizer and at least a portion of the condensate, prior to its at least partial revaporization in said vaporizer, is recycled into the regeneration column to a section located above the entrance point for the loaded scrubbing medium, is withdrawn again still above the entrance point for the loaded scrubbing medium, and is then passed to said vaporizer.
