Claim 0:
1. An integrated process for upgrading a hydrocarbon oil feed stream utilising a delayed coker, steam enhanced catalytic cracker, and an aromatics complex, 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;
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 light C5+ hydrocarbon stream, and a heavy C5+ hydrocarbon stream;
steam enhanced catalytically cracking the light C5+ hydrocarbon stream 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 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 the aromatics complex; and
processing the naphtha product stream in the aromatics complex to produce benzene and xylenes, and wherein
a ratio of gas hourly space velocity of steam to gas hourly space velocity of C5+ hydrocarbon stream in the first and second steam enhanced catalytic crackers is from 0.1 to 1.1 times steam to C5+ hydrocarbon stream.
