Control of anode spacing in alkali metal chloride electrolytic cells
Abstract
Abstract IN AN ALKALI METAL CHLORIDE ELECTROLYTIC CELL, THE SPACING BETWEEN THE ANODE AND THE MERCURY CATHODE IS CONTROLLED BY: (1) AT CERTAIN PREDETERMINED TIME INTERVALS, DRIVING THE NODE TOWARDS THE CATHODE UNTIL A SHORT CIRCUIT OCCURS (2) IMMEDIATELY WITHDRAWING AFTER THE SHORT CIRCUIT THE ANODE A PREDETERMINED DISTANCE FROM THE CATHODE (E.G., BY WITHDRAWING THE ANODE AT A FIXED RATE FOR A PREDETERMINED LENGTH OF TIME, A1) (3) THEN ADVANCING THE ANODE A DISTANCE LESS THAN THE DISTANCE WITHDRAWN (E.G., BY ADVANCING THE ANODE AT THE SAME RATE AS IN STEP (2), FOR A PREDETERMINED LENGTH OF TIME A2 LESS THAN TIME A1). A TIME DELAY CAN BE INTERPOSED BETWEEN THE WITHDRAWAL STEP (2) AND THE ADVANCEMENTS STEP (3), IF DESIRED, TO PERMIT REMOVAL OF ANODE PIECES FROM THE CATHODE.
