Apparatus for the treatment of gases or mixtures of gases and vapours in the presence of catalytic or purifying agents and for the reactivation of such agents

摘要

PICT:0345511/III/1 The apparatus described in the parent Specification is modified by the addition of a nest of tubes or an annular coil H located in the catalytic or purifying agent, preferably between the inlet rose E and outlet rose G for the regenerating agent. The coil serves to circulate a cooling agent during the regeneration process, and a heating agent when the catalytic or purifying process is in operation.
