1. An integrated process for upgrading a hydrocarbon oil feed stream, the method comprising:
solvent deasphalting the hydrocarbon oil stream to form at least a deasphalted oil stream and heavy residual hydrocarbons, the heavy residual hydrocarbons comprising at least asphaltenes;
processing the heavy residual hydrocarbons in a gasification unit to form syngas and gasification residue;
hydrotreating 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 in a first steam enhanced catalytic cracker to form a light steam enhanced catalytically cracked product comprising olefins, BTX, naphtha, or combinations thereof;
steam enhanced catalytically cracking the heavy C5+ hydrocarbon stream in a second steam enhanced catalytic cracker to form a heavy steam enhanced catalytically cracked product comprising olefins, BTX, naphtha, or combinations thereof;
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;
passing the naphtha product stream directly to an aromatics complex; and
processing the naphtha product stream in the aromatics complex to produce benzene and xylenes, and wherein
a first ratio of gas hourly space velocity of steam to gas hourly space velocity of light C5+ hydrocarbon stream in the first steam enhanced catalytic cracker is less than a second ratio of gas hourly space velocity of steam to heavy C5+ hydrocarbon stream in the second steam enhanced catalytic cracker,
the first ratio is from 0.2 to 0.8, and
the second ratio is from 0.8 to 1.0.
