ABSTRACT:
Gas treatment such as scrubbing or purificatory heating is carried out by treatment means in permanent gaseous communication with one end face of a rotary regenerative heat exchanger. At the other end face conventional inlet and outlet gas collecting arrangements are provided. A plenum chamber beyond or containing the treatment means allows for flow reversal of the gas treated, so that it may repass through the heat exchanger. Since collecting arrangements are provided at only one end face, the concomitant sealing arrangements need only be provided at that end face, and the rest of a support structure for the heat exchange mass (and which may also support at least some of the further treatment means) may be made of materials chosen solely with a view to resisting the physical and/or chemical conditions likely to be encountered.
