The fluid circulating in conduit 1 comprises hydrocarbons, as well as acid compounds to eliminate, such as CO2, H2S, the COS or of the mercaptans. The fluid circulating in conduit 1 is put in contact in zone ZA with an aqueous suspension of HDL or mixed oxides resulting from the moderated heat treatment of the HDL, arriving by the conduit 2.La aqueous suspension not only makes it possible to collect CO2 and H2S, but also the COS and the mercaptans. The fluid impoverished of acid compounds is evacuated by conduit 4. The aqueous suspension charged in acid compounds is sent by conduit 3 in the zone of regeneration RE.
