Abstract:
A process for the direct production of essentially dry halogen gas from essentially anhydrous hydrogen halide, comprising:(a) providing molecules of essentially anhydrous hydrogen halide to an inlet of an anode of an electrochemical cell;(b) oxidizing the molecules of essentially anhydrous hydrogen halide at the anode to produce essentially dry halogen gas and protons;(c) transporting the protons through an ionically conducting membrane of the electrochemical cell, wherein the ionically conducting membrane has a passage therein;(d) flowing a fluid into fluid communication with the passage in the ionically conducting membrane; and(e) reducing the transported protons at a cathode of the electrochemical cell.
