Factors affecting the level of recycled oil
Currently, many catalytic cracking units operate with their re-refining tanks filled to capacity; do you still maintain a certain liquid level there?
The reprocessing amount is an important parameter; how can full-tank operation be used in this case?
It is true that the amount of reprocessed oil is an important parameter, but is there necessarily a close connection between this and the operation of filling the reprocessed oil tank?
Of the previous three catalytic units, two were operated at full capacity!
May I ask, do you recover heat from refining? Or as a heat source?
It is related to factors such as the level of recycled oil, the properties of the feedstock, the degree of cracking, catalyst activity, and the distribution of products
We also operate with the refinery tank filled to capacity; once it’s full, the material flows automatically from the gas return line into the distillation tower
If operating at full tank capacity, are the recycle oil return column and the second intermediate return column still needed?
