PROCESS FOR ENRICHING A GASEOUS EFFLUENT WITH ACID GASES

摘要

The present invention relates to a process for enriching a gaseous effluent with acid compounds that comprises the following steps: a feed gas and a mixture of at least two liquid phases that are immiscible with each other, including one aqueous phase, are fed into a contacter R1, wherein the feed gas contains at least some acid compounds; predetermined pressure and temperature conditions for the formation of hydrates consisting of water and the acid compounds are established in said contacter; the hydrates are transported in a dispersion in the phase that is immiscible with the aqueous phase by pumping P1 to a flask R2 for dissociation of the hydrates; conditions for dissociation of the hydrates are established in the flask; and the gas generated by the dissociation, which is enriched with acid compounds compared to the feed gas, is discharged.
