Process and apparatus for hydroprocessing with two product fractionators
Abstract:
A process and apparatus are disclosed for recovering hydroprocessing effluent from a hydroprocessing unit utilizing a hot stripping column and a cold stripping column. A light fractionation column fractionates naphtha from kerosene predominantly from a cold stripped stream. A heavy fractionation column fractionates diesel from unconverted oil predominantly present in a hot stripped stream. Only the hot hydroprocessing effluent is heated in a fired heater prior to entering the heavy fractionation column, resulting in substantial operating and capital savings.
