What determines the outlet temperature of the hydrocracking fractionator?

Personally, I think it is determined by the product cut points and the load at the top of the fractionation tower; I’m not sure if that’s correct
The feed location and feed temperature of the material during the design of the distillation tower.
Of course, it is determined based on the product process. Nowadays, distillation towers usually have auxiliary towers such as jet fuel towers, diesel towers, and mid-stage reflux towers; generally, the load on the tower top is not related to the tower height, as the initial feed is quite light.
