1. An integrated process for upgrading a hydrocarbon oil feed stream utilizing a delayed coker, steam enhanced catalytic cracker and a dehydrogenation unit, 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 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, benzene, toluene, xylene, naphtha, or combinations thereof; and
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, benzene, toluene, xylene, naphtha, or combinations thereof, and wherein,
a first ratio of gas hourly space velocity of steam to gas hourly space velocity of the 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 gas hourly space velocity of the 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.
