摘要

A process for the regeneration of a loaded washing liquid, which consists of a plant for gas desulphurisation, and h₂S, co and metal carbonyls, from the laden scrubbing liquid co by expansion and / or stripping at least partially removed in the washing liquid and metal sulfides, the metal sulfides, at least partially out of the washing liquid is removed, the washing fluid by a regeneration is conductive and regenerated washing liquid into the returns gas desulphurisation, characterized in that the washing liquid for the removal of metal sulfides, for a dwell time in the range from 1 minute to 10 hours in a agglomerierbehälter with electrodes and an electrical field with a field strength of 10 to 5000 v / m between two adjacent electrodes, metal sulfides, on at least one electrode to agglomerate and agglomerated metal sulfides removed from the container.
