Abstract:
A regenerative apparatus for process fluids comprising:a first chamber having an inlet port and an outlet port; a second chamber having an inlet port and an outlet port; a first regenerative compartment including a regenerative material, the first regenerative compartment having an inlet port in communication with the outlet port of the first chamber and an outlet port in communication with the inlet port of the second chamber; a second regenerative compartment including a regenerative material, the second regenerative compartment having an inlet port in communication with the outlet port of the first chamber and an outlet port in communication with the inlet port of the second chamber; and a valve in the form of at least one flexible movable endless belt, the belt being looped around at least one of the chambers such that a portion of the belt is located between and external to both the chamber and the compartments, the belt comprising a solid zone and a plurality of flow through apertures positioned thereon such that movement of the belt successively opens fluid communication pathways in a predetermined configuration between selected ports of the first and second chambers and selected ports of the first and second regenerative compartments when a flow through aperture is located therebetween, and closes the fluid communication pathways when a solid zone is located therebetween.
