摘要:
An integrated process for upgrading a hydrocarbon oil feed stream includes solvent deasphalting the hydrocarbon oil stream to form at least a deasphalted oil stream and heavy residual hydrocarbons, delayed coking the heavy residual hydrocarbons to form petroleum coke and a delayed coker product stream; 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 to form a light steam enhanced catalytically cracked product stream including olefins, benzene, toluene, xylene, naphtha, or combinations thereof; and steam enhanced catalytically cracking the heavy C5+ hydrocarbon stream to form a heavy steam enhanced catalytically cracked product including olefins, benzene, toluene, xylene, naphtha, or combinations thereof.
