Abstract
A process is disclosed for reducing loss of hydrogen in solution to the fractionation section of a hydroprocessing unit. The hot flash overhead vapor bypasses the cold flash drum and may be treated with the cold flash vapor stream from the cold flash drum to recover hydrogen. Substantial conservation of hydrogen gas is achieved.
