How is the impurity content of the feedstock controlled in hydrorefining?

The filter only indicates 25μm, with no specific steps or information regarding the filtration process; please provide an explanation.

For automatic backwash filters, once the backwash pressure difference, pressurization time, and backwash time are set, it’s ready to use. Filter out mechanical impurities of about 25μm.

The filter only indicates 25μm, meaning it filters out only particles with a diameter larger than 25μm.

25 microns is likely an overly low filtration precision; it should be at least 10 microns

So which manufacturer’s filters are you using?

Yes, yes, that’s exactly what it says above. Thank you

The precision of hydrogenation filters is generally 25 microns. As for the control of impurities in the raw materials, specific quality requirements apply; this can be seen from the raw material analysis reports, which include elements such as S, N, Cl, and water. Of course, the boiling range also needs to be under control

Of course, the higher the precision, the better, but it still depends on the properties of the raw materials. If there are too many impurities in the raw materials, too high a precision can actually affect production due to the frequent need to clean the filters

Based on the filter differential pressure, backwashing occurs when the set differential pressure is reached; in addition, there is also forced backwashing at a set time – that is, backwashing takes place automatically after the specified time has passed, even if the differential pressure has not reached the set value.
