DISTILLATION OF CRUDE OIL ABSTRACT OF THE DISCLOSURE An entire crude oil stream is preheated by various sources of heat and brought to final temperature by a furnace. At this highest temperature, the stream is flashed into two portions, the heavier portion used only as a source of sensible heat for conser- vation, The vaporized fractions have their heat recycled into the crude oil stream and are then fractionated to extract a product of desired boiling range, flash point, and vapor pressure. The frac- tionation column is heated by the heavier, separated portion of the stream and refluxed by heat exchange with the crude oil stream.
