Apparatus 10 for the generation of chlorine gas, hydrogen gas and a sodium hydroxide solution by electrolysis of a sodium chloride solution comprises an electrolytic cell 12 having an anodic compartment 30 containing an anode and having an inlet 42 for the sodium chloride solution and an outlet 40 for the depleted sodium chloride solution, a cathodic compartment 18 containing a cathode and having an inlet 30 and an outlet 24 for the sodium hydroxide solution, and an ion permeable membrane 50 separating the anodic compartment 20 and the cathodic compartment 18, a first container 14 for the sodium chloride solution having an outlet 52 connected to the inlet 42 of the anodic compartment 20 and an inlet 58 connected to the outlet 40 of the anodic compartment 20, and a second container 16 for the sodium hydroxide solution having an outlet 70 connected to the inlet 30 of the cathodic compartment 18 and an inlet 76 connected to the outlet 24 of the cathodic compartment 18. Circulation of the liquids between the anodic compartment 20 and the first container 14 and between the cathodic compartment 18 and the second container 16 is caused solely by the generation of the chlorine gas and the hydrogen gas respectively. |
