Abstract
A process is described for the production of chlorine directly at the site where it is intended to be used and at the required rate. Hazards associated with the transport and storage of large quantities of liquefied chlorine under pressure are thus eliminated. The chlorine is produced electrochemically from a chloride containing electrolyte which is maintained at a pH no higher than 6, where the chlorine compounds are present as chloride and hypochlorous acid.
Claims19
An apparatus for producing chlorine, said apparatus comprising:
- an electrolyzer having one or more electrolytic cells each containing at least one cathode and at least one anode,
- a gas stripping column wherein said electrolyzer is in fluid communication with said gas stripping column,
- means for removing Cl.sub.2 and H.sub.2 from said gas stripping column,
- means for circulating an electrolyte from said gas stripping column through said electrolyzer to said gas stripping column, and
- a rectifier for providing DC current to said electrolyzer.
An apparatus for producing chlorine, said apparatus comprising:
- an electrolyzer having one or more electrolytic cells each containing at least one cathode and at least one anode,
- a gas stripping column wherein said electrolyzer is in fluid communication with said gas stripping column,
- said gas stripping column containing a demister, a gas/liquid disengagement section, a packed section, and a basin,
- a pH controller provided in said basin of said gas stripping column,
- means for removing Cl.sub.2 and H.sub.2 from said gas stripping column,
- means for circulating an electrolyte from said gas stripping column through said electrolyzer to said gas stripping column, and
- a rectifier for providing DC current to said electrolyzer.
