How can fine coke powder be completely separated from coker diesel and wax oil during transportation?
Thread Content
The characteristics of coking units mean that coked diesel and wax oil contain coke particles of various diameters. It is uncertain whether filters can completely remove these fine coke particles, as the mesh size of filters cannot be made too small. If this is not possible, then after the oil is stored in tanks, the fine coke particles will inevitably settle at the bottom; when the oil is pumped out, these particles will also be carried along. What are everyone’s thoughts on this issue?
Select an appropriate filter with backwash functionality; the mesh size of the filter should be determined based on the size of the coke particles carried along. Brands such as American Paul and Zhejiang Haimite are recommended.
Add more filters for filtration before proceeding with hydrogenation, and then use backwashing
The higher the mesh size, the greater the fluid resistance. How do manufacturers of similar devices choose the mesh size for their filters? Our facility is new, as are the storage tanks; since the tanks have not yet been emptied, it’s not possible to visually assess the situation. It seems that there might be a small amount of fine coke dust inside the tanks – is that correct?
The particle size of coke powder ranges from 100 nanometers to several micrometers, making complete separation impossible.
Hydrogenation units generally install 25μ automatic backwash filters before the feedstock enters the unit’s feed tank
