ABSTRACT:
A housing has a foraminous floor adapted to support a bed of adsorption particles. A plurality of baffles spaced above this floor subdivide the bed into a plurality of compartments. Impurity-carrying particles are fed to the compartment at one end of the elongated chamber and the particles overflow a weir at the compartment at the other end of the chamber. A hot gas is passed up through the bed in all of the chambers to deadsorb the particles and the baffles are spaced so that in the direction of flow each baffle projects more deeply into the bed to flow the flow toward the outlet end. A gas above the furthest upstream compartment is collected and condensed to recover useful constituents, and the gas from the other compartments is burned. It is possible to provide an upstream and a downstream compartment at an upper level and below them several downstream compartments, with the gas from the downstream compartments flowing up through the two upper compartments. The chamber has a length equal to at least twice its width and preferably equal to approximately the same multiple of its width as number of compartments it is divided into.
