Abstract
In ebullated bed hydroprocessing of a distillate hydrocarbon feedstock, it has been found that high pressure and low pressure heat exchange can be separated. Both the high pressure heat exchange and the fired heater fuel consumption are reduced. A control system provides for a constant distillate feedstock temperature in cooperation with heat integration.
