Factors affecting the 2% level of light lubricating oil in reduced-line hydrocracking

Thread Content

In hydrocracking, the factors affecting the 2% point of light lubricating oil in the reduced-pressure stream are, in my opinion, as follows: 1. The volume of material fed into the reduced-pressure tower: An increase in this volume leads to an increase in the temperature of the reduced-pressure tower, which in turn results in an increase in the 2% point of light lubricating oil. 2. Reflux flow at the top of the vacuum tower: An increase in this value leads to a decrease in the 2% point for light lubricating oil. 3. Temperature at the first-stage extraction: An increase in this value leads to an upward shift of the 2% point for light lubricating oils. 4. Reduce the steam flow rate in the primary stripping tower: an increase in this value leads to an upward shift of the 2% point for light lubricating oil. 5. Reducing the water vapor temperature in the primary stripping tower: an increase in this value leads to an upward shift of the 2% point for light lubricating oil. 6. Temperature of the steam at the top of the stripping tower entering the vacuum distillation column: An increase in this value leads to an upward shift in the 2% point for light lubricating oil. This is my analysis; everyone can discuss it to see what other factors have a significant impact on it and in what direction that impact occurs.
