Abstract
A process is disclosed for the cleaning of a clogged packed column. The packed column is utilized for gas cleaning in a scrubbing operation carried out with a scrubbing medium, and becomes plugged by deposits which form during operation. In order to be able to effectively and economically break up these deposits, the packed column is flooded, e.g., with a scrubbing medium, wherein the flooding fluid has a specific gravity greater than that of the particles of packing material. During the flooding of the packing, the deposits are broken up by flotation of the packing material. Preferably, the packed column can thus be utilized in scrubbing out H.sub.2 S in an oxidative scrubbing process in which sulfur deposits form.
