Apparatus for balancing electrolytic cell gas with circulating electrolyte

摘要

An apparatus used in high pressure electrolytic cell operation which allows a cell to be operated at high pressures while providing balanced interface pressures between circulating liquids and gases. Each liquid and gas compartment in the cell is connected to a holding tank. Gas pressure in the holding tank is allowed to build up to the pressure required for cell operation before it is released. Positive displacement pumps circulate liquids through the cell at a pressure equal to the pressure of gases contained in the holding tanks. Gases are back-pressured into the gas compartments of the cell at a pressure equal to the pressure of the gases contained in the holding tanks thereby balancing the pressures of gases and liquids in the cell while allowing for circulation of the liquids.
