Anode inlet pressure is too high
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 23:37 We are Asahi Kasei Ion Membrane. Recently, we found that the anode inlet pressure is too high, and the anode outlet hose is sometimes not smooth. Stopping the acid can improve it, but it seriously affects the purity of chlorine. This phenomenon did not occur before adding acid. Moreover, the air in the gas-liquid balance valve at the end of the tank obviously cannot escape. Please give me some advice~~~~~ Thank you ``:L :L :L This post was last edited by limingshuguang on 2008-1-3 21:43 ] # , , &
Can you describe the phenomenon more clearly?
Try lowering the liquid level of the salt water high-level tank appropriately.
Quickly analyze the brine indicators. The organic matter in the brine exceeds the standard, causing poor gas-liquid separation. It is estimated that the brine needs to be replaced.
Agree with the fourth floor. Check the organic content of the brine.
The organic matter content is not so easy to check! The general requirement for TOC is less than 10 ppm, but generally chlor-alkali companies do not have TOC meters. This thing is also very expensive, costing hundreds of thousands.
Is the sodium carbonate over-alkali content of primary brine very high? What causes the above problems to occur due to the excessive production of carbon dioxide?
I would like to ask if your salt treatment process is a traditional old process. It is probably because too much sedimentation aid (sodium polyacrylate or polyacrylamide) is added.
I think there are two reasons: First, there may be a problem with the balance pipe valve, and the gas cannot flow properly and balance. ； Second, it is possible that the sodium carbonate content in the brine exceeds the standard, the reaction produces more gas, and the release balance is not timely, causing the inlet pressure to be high. ；
