Abstract

<PICT:1088162/C6-C7/1> In a mercury cathode cell which is producing chlorine by electrolysis of alkali metal chloride solution the anode is set in accurately-spaced relationship to the mercury cathode surface by measuring the electrical conductance across the electrolyte gap between the anode and cathode, and then adjusting the spacing between anode and cathode so that the said conductance is brought to a predetermined value. The conductance measurement may be made by measuring the voltage drop between the cathodic base-plate and a probe a point on the anode conductor outside the cell, subtracting therefrom the reversible cell potential between anode and cathode and the chlorine over voltage, and in the latter case the potential drop is the anode connector structure, and relating the voltage drop hereby obtained to the measured current flowing. In the form shown the cathode is formed by a layer of mercury 5 flowing upon the metal base-plate 1. The anode comprises an anode block 6, and shaft 7 to which electric current is fed via bus-bar 9 and shaft 8. Conductivity measurements between anode and cathode are made using a titanium wire passing through a hole in the cell cover, which is sealed by a resilient bung 17, and attached to a titanium terminal screw 19, and a connection to the base-plate 1 at the point X. Adjustment of the anode is produced by rotation of the flanged screw adjuster 12. The cell may contain a plurality of anodes which may all be adjusted to a similar inter electrode gap as described above. The predetermined value of the electrolyte gap conductance may lie in the range 7,000-10,000 mho/m2 of cathode surface.
