Abstract
A hot stripped hydroprocessed stream from a stripper column may be sent directly to a vacuum fractionation column instead of being first processed in an atmospheric fractionation column. If a separate warm stripper column is used, both the warm stripped stream and a hot stripped stream may be fractionated in the same fractionation column, particularly a vacuum fractionation column.
