Abstract
An electrolytic cell is provided that is particularly suitable for the production of oxy -halogen compounds such as sodium chlorate by electrolysis of an alkali metal halide such as sodium chloride. A cell chamber is provided containing an electrode assembly and is connected for the circulation of electrolytic solution to a cooling and concentrating chamber. Gas communication between the cell chamber and the cooling and concentration chamber is substantially avoided. Gas evolved during the electrolysis is separately removed from the cell chamber and is preferably scrubbed. Gas such as air is swept through the cooling and concentration chamber so as to provide at least part of the cooling requirements for removing the heat generated during the electrolysis and to evaporate, thereby concentrating the electrolytic solution. This takes advantage of the sensible heat of the electrolytic solution for the evaporation of such solution.
