1. An integrated system for the conversion of hydrocarbon oil feed stocks utilizing a delayed coker, steam enhanced catalytic cracker, and an aromatics complex comprising a catalytic reformer and a transalkylation unit, comprising:
a solvent deasphalting unit configured to separate a hydrocarbon oil stream into at least a deasphalted oil stream and heavy residual hydrocarbons, the heavy residual hydrocarbons comprising at least asphaltenes;
a delayed coker fluidly connected to the solvent deasphalting unit and configured to de-coke the heavy residual hydrocarbons into at least a petroleum coke and a delayed coker product stream;
a hydrotreater fluidly connected to the solvent deasphalting unit and the delayed coker and configured to hydrotreat at least the deasphalted oil stream and the delayed coker product stream to form a light C5+ hydrocarbon stream and a heavy C5+ hydrocarbon stream;
a first steam enhanced catalytic cracker fluidly connected to the hydrotreater and configured to crack at least a portion of the light C5+ hydrocarbon fraction to form a light steam enhanced catalytically cracked product; and
a second steam enhanced catalytic cracker fluidly connected to the hydrotreater, in parallel with the first steam enhanced catalytic cracker, and configured to crack at least a portion of the heavy C5+ hydrocarbon fraction to form a heavy steam enhanced catalytically cracked product;
a product separator fluidly connected to the first and second steam enhanced catalytic crackers and configured to produce an olefin product stream, a naphtha product stream, and a BTX product stream;
the catalytic reformer fluidly connected immediately downstream of the product separator and configured to catalytically reform the naphtha product stream to produce a reformate stream comprising benzene, toluene, and xylenes; and
the transalkylation unit fluidly connected to the catalytic reformer and configured to upgrade the toluene in the reformate stream to produce additional benzene, xylenes, or both, 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.
