Integrated fixed bed hydroprocessing, delayed coking and pyrolysis process to produce chemicals and petroleum coke

A system for converting whole crudes and other heavy hydrocarbon streams to produce olefins, the system comprising:

• a separation unit for separating a whole crude into at least a light boiling fraction, a medium boiling fraction, and a high boiling residue fraction;
• a delayed coking unit for processing the high boiling residue fraction and producing a delayed coking liquid product and an anode grade coke product;
• a conditioning system for destructively hydrogenating the medium boiling fraction and the delayed coking liquid product to produce a hydrotreated effluent;
• a steam cracker unit for converting the hydrotreated effluent and the light boiling fraction into one or more light olefins and a pyrolysis oil.

A process for converting whole crudes and other heavy hydrocarbon streams to produce olefins and/or aromatics, the process comprising:

• separating a hydrocarbon feedstock in a first integrated separation device into at least a light boiling fraction, a medium boiling fraction, and a high boiling residue fraction;
• hydrocracking the high boiling residue fraction in a first resid conditioning unit, comprising a resid hydrocracking system, to produce a hydrocracked effluent;
• processing the hydrocracked effluent in a delayed coking unit to recover an anode grade coke product and a delayed coking liquid product;
• hydrocracking the delayed coking liquid product and a pyrolysis oil in a second resid conditioning unit, comprising a resid hydrocracking system, to produce a second hydrocracked effluent;
• separating the hydrocracked effluent and the second hydrocracked effluents in a second integrated separation device to produce the resid 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.
