1. A process for converting whole crudes and other heavy hydrocarbon streams to produce olefins and/or aromatics, the process comprising:
feeding a hydrocarbon feedstock into a heater, producing a pre-heated hydrocarbon feedstock;
separating the pre-heated hydrocarbon feedstock in a separator into a light boiling fraction and an intermediate fraction;
feeding the intermediate fraction to the heater, producing a heated intermediate fraction;
feeding a hydrogen stream to a hot hydrogen stripper;
separating the heated intermediate fraction in the hot hydrogen stripper into a medium boiling fraction and a hot hydrogen stripper bottoms fraction;
cooling the hot hydrogen stripper bottoms fraction via indirect heat exchange against the intermediate fraction producing a high boiling residue fraction;
hydrocracking the high boiling residue fraction and pyrolysis oil in a first conditioning unit, comprising a resid hydrocracking system, to produce a hydrocracked effluent;
separating the hydrocracked effluent in a second integrated separation device to produce a fuel oil fraction and a partially conditioned fraction;
destructively hydrogenating the medium boiling fraction and the partially conditioned fraction in a second conditioning unit to produce a steam cracker feedstream;
feeding the steam cracker feedstream and the light boiling fraction to a steam cracker to convert hydrocarbons therein into one or more light olefins and the pyrolysis oil.
