1. A hydrotreating process comprising:
hydrotreating a hydrocarbon feed stream in a hydrotreating reactor to provide hydrotreating effluent stream;
separating said hydrotreating effluent stream into a cold separator stream and a hot separator stream;
stripping said cold separator stream in a cold stripper column to provide a cold stripped stream;
stripping said hot separator stream in a hot stripper column to provide a hot stripped stream;
fractionating said hot stripped stream in a product fractionation column;
bypassing said cold stripped stream around said product fractionation column; and
recycling a condensed overhead stream from said product fractionation column to said cold stripper column.
