Ferrous sulfide passivation solution
Thread Content
We urgently need a ferrous sulfide passivation solution when the device is shut down, thank you.
Generally, it needs to be contracted to a third party. A special passivation liquid is circulated into the tower. It is also used to wash the tower. To prevent spontaneous combustion, if you don’t want to spend such money, you can pump cooling water into the tower during shutdown to cool the packing or trays. However, this requires It should be pumped regularly and regularly, and the pumped water should be drained. Of course, the load of the sewage treatment plant should be considered before draining. The other thing I think is to use diesel to replace the raw material and circulate it in the tower during shutdown. After the oil is removed, it is fully cooked and the cooling water is pumped.
Same problem, has the poster found a good solution?
