ABSTRACT:
A method and apparatus for operating an electrolysis plant including a plurality of furnaces in which the anode spacing of each furnace is controlled by means of a computer as a function of furnace resistance. A desired furnace resistance is varied as a function of the furnace current yield, the optimum of which is given by a selected number of furnace voltage variations which exceed a specified voltage level, and, in addition, as a function of furnace energy consumption as indicated by the furnace resistance gradient, the rate of change of that gradient, and the difference between the expected furnace metal production with respect to long-term current yield and the measured furnace metal production.
