Abstract
Abstract Apparatus for contacting a gas with a solid material comprising an assembly of tubular containers for the solid material which are mounted in a housing provided with a gas inlet and a gas outlet. The containers have gas-permeable walls and are positioned so that gas channels are formed along the containers by the walls of adjacent containers and/or the walls of adjacent containers and the walls of the housing. To construct the apparatus, a number of corrugated parallel gauze plates may be tack-welded together such that each plate forms a mirror image of an adjacent plate. When in use some of the channels thus formed contain solid material, and others are used as gas channels.
