The fluid circulating in conduit 1 comprises hydrocarbons, and also acidic compounds to be removed, such as CO2, H2S, COS or mercaptans. The fluid circulating in conduit 1 is brought into contact, in zone ZA, with an aqueous suspension of LDH or of mixed oxides derived from moderate heat treatment of the LDHs, being supplied via conduit 2. The aqueous suspension makes it possible not only to capture the CO2 and H2S, but also the COS and the mercaptans. The fluid depleted of acidic compounds is discharged via conduit 4. The aqueous suspension loaded with acidic compounds is sent, via conduit 3, to the regeneration zone RE. |
