Abstract
The present invention is directed to a process and apparatus for controlling the pressure load on gaskets of an electrolysis cell by comparing the internal cell pressure to the pressure of the hydraulic fluid to the cell compressor and activating a controller for adjusting the pressure to a set point based on the data obtained by the comparison. The apparatus includes a hydraulic compressor adapted for pressing cell members together, a pressure sensor for measuring the pressure inside the electrolysis cell, a pressure sensor for measuring the pressure in the compressor, and a controller for controlling the amount of hydraulic fluid to and from the compressor.
