Abstract
A method for removing by adsorption undesirable components such as sulphur dioxide, from waste gases, particularly flue gas. Activated carbon is located between two perforated walls. The flue gas to be cleaned, traverses the activated carbon. During shutdown or low-load operation of the plant, the flue gas is already cleaned in the adsorber or still remaining in the associated apparatus section, are fed back and are passed once more through the activated carbon. The fed-back flue gases may be cooled before being passed once more through the activated carbon. An inert gas at a pressure substantially above atmospheric may be injected in the adsorber installation. The temperature and/or the oxygen content of the fed-back flue gas is monitored. The activated carbon fill is divided by heat-insulated partitions into individual sections which are charged separately with fed-back flue gas.
