Abstract:
1. A method for producing distillate products, comprising: hydrotreating a feedstock under effective hydrotreafing conditions; passing at least a portion of the hydrotreated feedstock into a first separate volume of a divided wall fractionator; fractionating the at least a portion of the hydrotreated feedstock at a cut point of at least about 260° C. to form a heavy diesel fraction and a first light diesel fraction, the heavy diesel fraction being withdrawn from the first separate volume of the divided wall fractionator; dewaxing the heavy diesel fraction under effective dewaxing conditions to produce a dewaxed heavy diesel fraction having a cloud point of about −10° C. or less; passing the dewaxed heavy diesel fraction into a second separate volume of the divided wall fractionator; and fractionating the dewaxed heavy diesel fraction to form at least a heavy diesel product withdrawn from the second separate volume, the fractionation further producing a second light diesel fraction, wherein the first light diesel fraction and the second light diesel fraction form a combined light diesel fraction that is withdrawn from a common volume of the divided wall fractionator.
