How is the feed temperature of the hydrocracking fractionation tower determined?
Thread Content
As the title suggests: How is the feed temperature for the hydrocracking distillation column determined? I would appreciate guidance from those with expertise; let’s exchange ideas and discuss this together.
OP, has this issue been resolved?
It is related to the light oil yield of the distillation tower; since the thermal load of the distillation tower is essentially concentrated entirely in the feed heater, in order to achieve a certain level of light oil yield, there must be a certain degree of vaporization rate at the inlet, which in turn determines the inlet temperature
This problem is very complex; in my opinion, it must be related to many factors. 1. The vaporization rate required by the design 2. The distillation scheme 3. The operating pressure of the distillation tower, and so on
Could the boiling range of the raw material be considered?
While ensuring product quality and yield, try to reduce the temperature in order to lower the load on the heating furnace
