ABSTRACT:
Apparatus for producing chlorine gas comprising a plurality of separately housed electrolytic cells containing bimetallic electrodes electrically connected in series. Each electrolytic cell is divided into an anode and a cathode compartment separated by an ion permeable membrane which is impermeable to gases and water. Each cell housing contains passageways for simultaneously delivering a pure alkali metal chloride brine solution to the anode compartments and transporting chlorine gas produced at the anode and spent brine solution from the anode compartments. Passageways are also provided in each cell housing for delivering deionized water to the cathode compartments and conveying hydrogen gas produced at the cathode and an alkali metal hydroxide solution from the cathode chamber. Approporiate piping is provided for delivering brine solution and deionized water to the cell housing and conveying chlorine gas and spent brine and hydrogen gas and an alkali metal hydroxide solution from the cell housing. A positive direct current is supplied to the anode of one end cell of the apparatus and a negative direct current is supplied to the cathode at the other end cell of the apparatus.
