Is the backwashing frequency of the backwash filter for coking wax oil high? Is the amount of contaminated oil large? How to deal with contaminated oil?
Are you using the equipment there for online backwashing of coking bottom circulation filters?
Our bottom circulation oil filter does not have online backwashing, but it can be backwashed using steam online into the dirty oil line.
The contaminated oil goes to the contaminated oil tank. Generally, we send such oil back to the coking unit, which indirectly reduces the actual load on the coking process; therefore, the coking unit itself needs to first clean the oil.
The backflush frequency depends on the content of gums and impurities in the wax oil; the contaminated oil is sent to the oil waste tank.

The backwash filter should be triggered for backwashing based on time or pressure difference; it will backwash when the pressure difference reaches the value set by the control system, or when a specified amount of time has passed. If the impurity content is high, there will be continuous backflow, resulting in low efficiency. There are now automatic cleaning filters with a minimum pore size of 15 microns; those interested can contact jwL5884284@126.com
The backflush frequency and the amount of contaminated oil are primarily determined by the design. When the actual operating conditions match those specified in the design, the frequency and amount of contaminated oil will be similar to those designed. However, if the operating conditions differ significantly, things change. This is why, with the same PALL backflushing device, it works well in some places but not at all in others; frequent backflushing can ultimately lead to damage to the quick-opening ball valve or trigger alarms due to excessive pressure drops as soon as it is opened
