The chlorine-hydrogen pressure difference in the electrolyzer is low
Thread Content
Our company has six Taibei Petrochemical membrane-gap electrolyzers; among them, the chlorine-hydrogen pressure difference in four of these electrolyzers is less than 3 KPa, while that in the two additional electrolyzers is less than 4 KPa. I would like to ask the experts here, how should I handle this?
The pressure difference between chlorine and hydrogen in the main pipe is shown as 4 KPa, but in reality it is less than 4 KPa; the readings for the pressure of chlorine or hydrogen in the main pipe are inaccurate – this may be due to poor insulation that has caused freezing. It is possible to refer to the pressure readings for chlorine and hydrogen in individual tanks
Increase the main pipe pressure difference, while calibrating the pressure transmitter and making adjustments
The chlorine-hydrogen pressure difference in the electrolyzer should be 4 KPa
The pressure losses vary due to factors such as the length of the pipeline and the flow rate. Attention should also be paid to the slope of the pipeline and whether there is any accumulated liquid
