ABSTRACT:
Economies in capital cost and operation of a hydrocarbon refining unit for desulfurization of diesel fuel are provided by a heat exchange sequence which eliminates the need for a fired heater on the product fractionation zone. The feed to the fractionation zone is heat exchanged twice against both the effluent bottoms stream of the fractionation zone and the reaction zone effluent stream.
