Abstract
A process is disclosed for reducing loss of hydrogen in solution to the fractionation section of a hydroprocessing unit. The hot liquid stream is stripped with an inert gas in a hot flash stripper to urge hydrogen into the hot flash vapor stream. Substantial conservation of hydrogen gas is achieved.
