A PROCESS FOR THE PRODUCTION OF HCL GAS FROM CHLORIDE SALTS AND FOR THE PRODUCTION OF CARBOHYDRATES

摘要

A process for the co-production of gaseous HCI and a salt product comprising a cation and an anion, which process comprises the steps of a. providing an aqueous solution comprising protons, chloride anions, and cations and anions of the salt product, b. bringing the solution into contact with a substantially immiscible extractant, the extractant comprising: 1) an oil soluble amine, which amine is substantially water insoluble both in free and in salt form; and 2) a carrier solvent for the amine; whereupon HCI selectively transfers to the extractant to form an HCI- carrying extractant and a chloride depleted aqueous solution containing the salt product; c. separating the HCI-carrying extractant from the chloride-depleted aqueous solution; and d. distilling HCI from the separated HCI-carrying extractant to form gaseous HCI and HCI depleted extractant.
