A PROCESS FOR THE RECOVERY OF HYDROCHLORIC ACID

摘要

The Invention provides a process for the recovery of gaseous HCI comprising: a) providing an HCI-carrying extractant comprising: (i) an oil soluble amine which amine is substantially water insoluble both in free and in salt form; and (ii) a solvent for the amine and organic acid; b) contacting the HCI-carrying extractant with at least one non-volatile mineral acid, and c) stripping gaseous HCI, whereby HCI-depleted extractant and gaseous HCI are formed.
