摘要：An improved method for the distillation of a feed stream (12) containinghydrocarbon components, which method is directed toward the production of a bottomproduct stream (26) and an overhead product stream (16), both with desired

specifications, which method comprises recycling a minor portion of the bottom productstream typically, but not necessarily, derived from said separation directly to a refluxcondenser for the overhead product stream of said method, in order to effect a savingsin energy in said distillative method, such as by adjusting the column operatingconditions, such as the column operating pressure or the top or bottom operatingtemperatures of said column.
