<p>There is described a method of regenerating carbonate granules used in a gas cleansing plant in which gas to be cleansed flows through a bed of carbonate granules, e.g. mineral granules rich in limestone and having an approximate size of 5-10 mm, by removing from said granules surface coatings formed by impurities, such as SOx-impurities, in the gas cleansing process. The granules removed from the bed ar worked mechanically in a manner which subjects the granules to pressure forces and shear forces. The mechanical working process is effected by the mutal infuence of the carbonate granules on one another in a mill (7) having a rotor (7") provided with outwardly projecting elements (7'''), said elements transmitting the energy of rotor motion to the carbonate granules (7'), whereafter regenerated carbonate granules having an approximate size of 5-10 mm are separated from the thus worked material and returned to the bed.</p> |
