Apparatus and process for producing chlorine gas and for employing such chlorine gas for the production of chlorine water

An apparatus for producing chlorine gas and for employing said chlorine gas for the production of chlorine water, said apparatus comprising:

• an electrolytic cell for the electrolysis of a sodium chlorine solution, said cell comprising a cathode compartment having therein a cathode for producing hydrogen during electrolysis and an anode compartment having therein an anode for producing chlorine gas during electrolysis, single conduit means at the bottom of said cell for charging sodium chloride solution into said compartments and for discharging therefrom solutions resulting from electrolysis, and a porous partition substantially separating said compartments, said partition having a lower end terminating above the bottom of said cell at said charging and discharging means, such that lower ends of said compartments are in free communication;
• an absorption tower for contacting chlorine gas produced in said anode compartment with water, and thereby for forming chlorine water;
• and
• means for supplying the hydrogen and chlorine gas produced in said compartments to said absorption tower, and for dynamically balancing the pressure in said compartments and thereby preventing mixing of the products of electrolysis from said cathode and anode compartments, said supplying and balancing means comprising a chamber connected to upper ends of said compartments for receiving therefrom and mixing said hydrogen and chlorine gas, and a conduit for passing the thus mixed gases to said absorption tower.
