Liquid degassing means and method

A method for degassing a liquid-gas mixture in an electrolytic system, said method comprising the following steps:

• providing an enclosed tank for use in an electrolytic system requiring the degassing of a liquid-gas mixture, the tank being adapted to contain a liquid, the liquid having a normal operating level at an intermediate height within the tank, wherein:
• one or more baffle(s) in the tank define a first region and a second region, wherein the first region accommodates relatively turbulent conditions for the liquid, and the second region accommodates relatively calm conditions for the liquid, and
• a liquid transfer gap is present so liquid can transfer from the first region to the second region, and
• a gas transfer gap is present to allow gas to transfer from the first region to the second region;
• causing the liquid-gas mixture to flow from an electrolyzer to the tank through an inlet, the inlet being to an antechamber of the tank, and the antechamber having an outlet which is above the normal operating level of the liquid,
• flowing the liquid-gas mixture through the antechamber outlet, the liquid-gas mixture then entering the first region, wherein:
• the liquid-gas mixture cascades into the first region,
• turbulence in the first region encourages the removal of gas dissolved in the liquid-gas mixture,
• allowing the substantially degassed liquid to flow from the first region to the second region via the liquid transfer gap, and
• causing the substantially degassed fluid to flow from the second region through a first outlet for use elsewhere in the electrolytic system, and
• removing gas from the tank via a second outlet, and
• providing a refill inlet for maintaining the liquid at a desired liquid level, and
• wherein a heating element or heat exchanger is provided in combination with a temperature sensor and a control unit for maintaining the temperature of the electrolytic system.
