ABSTRACT:
In a process of chlor-alkali electrolysis carried out in a diaphragm cells comprising pairs of interleaved anodes and cathodes, the cathodes being provided with openings and coated with a porous diaphragm resistant to corrosion, at least part of the said anodes being provided with hydrodynamic circular to produce circulation of the anodic brine, the cell having inlets for feeding the fresh brine, and outlets for the removal of produced chlorine, hydrogen and caustic, the improvement comprising controlling the oxygen content in the chlorine and chlorate concentration in the caustic independently from the the fresh brine introduced and the concentration of the the brine by adding an aqueous solution of hydrochloric acid to the brine in the anodic compartment of the cell through a distributor positioned over the hydrodynamic circulator.
