Abstract
Two or three strippers are used to strip three hydroprocessed effluent streams, perhaps from a slurry hydrocracking reactor, separated by temperature instead of a single stripper to preserve separations previously made and conserving energy and reducing vessel size. A cold stripped stream may be taken as a diesel blending stock without further fractionation.
