ABSTRACT:
A method for removing particulate solids, such as catalyst fines, from a hot slurry oil having a gravity of 5.degree. API to 15.degree. API, an atmospheric pressure initial boiling point of from about 500.degree. F. to about 750.degree. F. and an atmospheric pressure end point of less than 1,000.degree. F. which entails mixing a preselected amount of the slurry oil with a preselected amount of a hot vacuum reduced crude oil having equilibrium flash vaporization characteristics such that when the mixture is subjected to a selected temperature in a vacuum tower maintained at a vacuum of from about 1.0 mm Hg to about 10.0 mm Hg, at least 85 volume percent of the slurry oil will be flashed overhead and not more than about 15% of the vacuum reduced crude oil will be flashed overhead, and the particulate solids will remain in the liquid bottoms.
