Abstract
A device for treating gaseous effluents from a catalytic cracking unit comprises at least one first stage for regenerating a catalyst used in a catalytic cracking process wherein the gaseous effluents issuing from a cracking catalyst regenerator are treated in a heat recovery unit (CR) including a treating chamber having an entrained bed. The absorbent introduced in this chamber has a 'fine' grain size ranging between 0.1 and 100 .mu.m and can be regenerated in the device downstream from heat recovery unit (CR).
