Adjustment of heat extraction from the second catalytic fractionation tower
Thread Content
Adjustment of heat extraction from the second catalytic fractionation tower: What factors are primarily used to determine the amount of heat extracted? How can it be ensured that the diesel components do not reach the re-refining system after adjustment?
Check the temperature of the oil taken out for re-refining and conduct a re-refining analysis. After the heat extraction from Unit 2 increases, it is possible to reduce the heat extraction from Unit 1 or the heat extraction from the slurry, in order to prevent the diesel extraction temperature from dropping.
