Abstract

In the treatment of gases before exhaust into the atmosphere for removal of pollutants such as acid gases, wherein such gases are passed through a filter having a layer of particulate material, eg nahcolite or nepheline syenite, on the ingoing side of the filter surface for the removal of acid gases by absorption and/or reaction, the filtered gases are recirculated until the integrity of the layer of particulate material has been established and the removal efficiency for acid gases has been optimized, eg the particulate material has been heated to an optimum temperature. The filter apparatus may comprise a plurality of filter sections each containing a plurality of filter tubes 28, means being provided to remove one section at a time from filter flow for cleaning of the bags, eg cake removal by shaker means 34, and then rebuilding of the particulate material layer and heating thereof using recycle conduit 52 and material supply 62. <IMAGE>
