Abstract:
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 conservation. 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 fractionation column is heated by the heavier, separated portion of the stream and refluxed by heat exchange with the crude oil stream.
