摘要:
An integrated process for upgrading a hydrocarbon oil feed stream utilizing a delayed coker, steam enhanced catalytic cracker, and an aromatics complex includes solvent deasphalting the hydrocarbon oil stream; delayed coking the heavy residual hydrocarbons; hydrotreating the delayed coker product stream and the deasphalted oil stream to form a C3-C4 hydrocarbon stream, a light C5+ hydrocarbon stream, and a heavy C5+ hydrocarbon stream; dehydrogenating the C3-C4 hydrocarbon stream to form propylene and butylene; steam enhanced catalytically cracking the light C5+ hydrocarbon stream; steam enhanced catalytically cracking the heavy C5+ hydrocarbon stream; passing at least a portion of the light steam enhanced catalytically cracked stream, the heavy steam enhanced catalytically cracked stream, or both to a product separator to produce a olefin product stream, a naphtha product stream, and a BTX product stream; and processing the naphtha product stream in the aromatics complex to produce benzene and xylenes.
