1. An integrated hydrocracking process for production of olefinic and aromatic petrochemicals from a hydrocarbon feedstock comprising crude oil, the process comprising:
treating the hydrocarbon feedstock comprising crude oil and a residual liquid product in a first hydrocracking zone in the presence of hydrogen under effective conditions producing a first effluent having an increased hydrogen content; separating the first effluent into a liquefied petroleum gas (LPG) comprising stream and a liquid phase stream; separating said LPG comprising stream into one or more streams chosen from a stream comprising hydrogen, a stream comprising methane, a steam comprising ethane, a stream comprising butanes, a stream comprising propane, a stream comprising C1-minus, a stream comprising C3-minus, a stream comprising C1-C2, a stream comprising C3-C4, a stream comprising C2-C3, a stream comprising C1-C3, a stream comprising C1-C4, a stream comprising C2-C4, a stream comprising C2-minus, a stream comprising C4-minus; further processing one or more of the streams obtained in a steam cracker unit and at least one unit chosen from a butanes dehydrogenation unit, a propane dehydrogenation unit, a combined propane-butanes dehydrogenation unit, or a combination of units thereof to produce mixed product stream(s); feeding the mixed product stream(s) from said steam cracker unit and said at least one unit, chosen from said butanes dehydrogenation unit, said propane dehydrogenation unit and said combined propane-butanes dehydrogenation unit, or a said combination of units thereof, to a second separation section; thermally cracking the liquid phase stream in a resid hydrocracking zone to produce a slurry intermediate product; separating the mixed product stream(s). |
