ABSTRACT:
An electrolytic cell for separating chlorine gas from other (foreign) gases, having an anode electrode, a cathode electrode, a gas impermeable (but liquid permeable) membrane interposed between the anode and cathode electrodes, an aqueous electrolyte, a housing, and a constant voltage power supply. The electrolytic cell may be constructed in either a rectangular or cylindrical geometry, and may be combined with other electrolytic cells to form a multiple cell system. In operation, a stream of chlorine and foreign gases enters the cell at the lower portion of the cathode electrode. The chlorine gas is dissolved into the electrolytic and electrochemically reduced into chloride ions. The chloride ions diffuse through the gas impermeable membrane, and are electrochemically oxidized at the anode into purified chlorine gas. The foreign gases do not participate in the above, and are vented from the cell.
