Abstract
A process and apparatus is disclosed for recovering hydrotreating effluent from a hydrotreating unit utilizing a hot stripper and a cold stripper. Only the hot hydrotreating effluent is heated in a fired heater prior to product fractionation, resulting in substantial operating and capital savings. The cold stripped stream from the cold stripper bottoms line may be passed directly to a diesel pool when VGO is hydrotreated in the hydrotreating reactor bypassing the product fractionation column.
