The issue of desulfurization foam
Thread Content
Our plant constantly experiences foam overflow during desulfurization. The foam is weak, and we dare not add regenerating gas – whenever we do, foam overflow occurs. The reaction tank is overflowing in large amounts, and the cause cannot be identified. Does anyone who knows the reason know how to deal with it? Please advise
We also feel that too much catalyst was added
Reduce the amount of desulfurization liquid, increase the air volume, and adjust the liquid level regulator downward
1. The discharge rate should be increased, with continuous discharge, in order to reduce suspended sulfur. 2. Control the catalyst content and recalculate; I estimate the main issue is that your output is insufficient – the level will drop after three days of continuous output
Adjust the vapor-liquid ratio properly. . . . . . . . . . . . . . . .
Send a test report to see what the level of suspended sulfur is, etc. How much hydroquinone and PDS should be added, and what method should be used for desulfurization?
What is a good range for the gas-liquid ratio?
Could you send over the test results, including a full analysis of the solution as well as your various operational parameters?
If measures such as gas-liquid ratio control are all in order, considering the use of an antifoaming agent is an option.
