Abstract

In a method for cleaning SOx-polluted flue gases from a combustion process, the flue gases are, in a gas-cleaning zone (20), passed through a gas-cleaning bed (22) of an SOx-absorbing substance which, once polluted and heated by the flue gases, is circulated out of and back to the gas-cleaning zone (20) in a circulation path which passes through a cooling zone (30), where the substance is directly contacted with a cooling medium in order to be cooled, and a separating zone (40), where sulphur pollutants are removed. The gas-cleaning bed (22) is gradually displaced into the cooling zone (30) where it instead forms a cooling bed (32) through which the cooling medium is passed. The bed is displaced through a channel (21, 50, 31) of annular cross section, such that the substance is fed as a tubular body (22, 53, 32) through the channel running through the gas-cleaning zone (20) as well as the cooling zone (30). The flue gases and the cooling medium are passed substantially radially through the bed in the gas-cleaning zone (20) and the cooling zone (30), respectively.
