Some questions about dispersants. .
Thread Content
During normal feeding, when the dispersant is added. The program will automatically stop when there are less than 4 kilograms left in the weighing tank. The feed pump will also stop. As a result, a portion of the dispersant with a lower concentration will remain at the pump inlet. If no material is added for a long time, will it have any effects if the dispersant remaining at the pump inlet at the time of adding material enters the tank??????
Modifications can be made in the program; after adding the dispersant, it should be rinsed with pure water.
In a proper design, flushing water is used for cleaning, and this flushing water is also pumped into the tank, so there is no issue of excessive residue of dispersant. If the company in question doesn’t have a design, it can be modified; there aren’t many issues with DCS control!
There will be no residual dispersant at all. According to the formula for the tank, the dispersant needs to be washed away using water during loading. What I’m referring to is the formula for a 70-cubic-meter tank; as for what LZ is talking about, I’m not sure which type of tank’s formula it is – you can mention that so that we can give more targeted advice.
After adding the dispersant, it is necessary to rinse with pure water; this serves two purposes: one is to clean the pipes, and the other is to ensure that the dispersant is fully added. This is especially important in cases where there are multiple reactors connected to the dispersant pipeline, as it helps prevent any residual dispersant from remaining in dead corners.
