Will increasing the amount of reprocessed oil affect the product yield?
Re-refined oil consists of components that are not suitable for cracking and are relatively heavy; if this is taken into account when calculating the crude oil input, it will certainly affect the overall yield. More importantly, the product obtained (gasoline) will have an increased level of olefins as well as a slightly higher sulfur content, so it is necessary to handle the situation accordingly.
Yes, it does help to increase the yield to some extent
The amount of re-refining oil should not be excessive; it should only be increased appropriately when there is a shortage of raw materials. Using too much of it brings no benefits
It depends on whether you need the product from the top of the tower or from the bottom. If it’s at the top of the tower, it will definitely affect the yield. If it’s at the bottom of the tower, the impact should be minimal
At a constant overall conversion rate, an increase in the recycle ratio leads to a decrease in the single-pass conversion rate, a decline in gasoline yield, an increase in diesel yield, an increase in the total light oil yield, and a reduction in the plant’s processing capacity.
