Abstract: Fluid medium such as light cycle oil, water, FCC slurry and decanted oil, improve this method for vacuum distillation of a petroleum product. The method may be used in the petroleum refining industry for fractionating of petroleum base stock in a vacuum column. The fluid medium prevents the formation of thermoset polymers and the resultant fouling of the wash beds in the vacuum column.
