ABSTRACT:
Heated hydrocarbon crude oil is passed into a first flash zone wherein it is separated into a first flash vapor and a first flash liquid. First flash vapor is water washed to remove soluble contaminants, and the resulting wash water and the first flash liquid are passed to a desalter. First flash liquid having substantial freedom from water soluble contaminants is passed from the desalter into a second flash zone wherein it is separated into a second flash vapor and a second flash liquid. The second flash liquid is passed into a conventional fractionation zone comprising a crude column and a vacuum column.
