Pressure control of the anode and cathode in diaphragm electrolyzers
Thread Content
I’m a newcomer to the chlor-alkali industry; my company is planning to launch a project that uses diaphragm electrolysis to process salt concentrated in wastewater, in order to produce hydrogen and chlorine, which can then be used to make hydrochloric acid. I have a question: what should be the pressure control at the cathode and anode of the electrolyzer? That is, what should be the pressure controls for the hydrogen outlet and the chlorine outlet? The electrolyzer is of type 16. The manual specifies a cathode pressure of 98–196 Pa and an anode pressure of 0–49 Pa. During installation, the manufacturer suggested a cathode pressure of around 50 Pa and an anode pressure of around -50 Pa. Seek an authoritative statement! ! !
What was said about the installation is correct: a slight negative pressure at the anode, and a slight positive pressure at the cathode. Type 16 diaphragm electrolyzer – quite old.
Managing diaphragm cells does require some attention; safety is no trivial matter.
