Abstract
An integrated process comprising to convert crude oil, comprising: converting crude oil (10) in a feed preparation facility (800) by separating the crude oil to a gas fraction (101), liquid fraction (102), and first residuum fraction in an atmospheric distillation unit (100); separating the 1st residuum to a vacuum gas oil fraction (202) and a second residuum (201) in a vacuum distillation unit (200); converting the vacuum gas oil fraction to a CU gas fraction (301,401), a CU liquid fraction (302), and an CU higher boiling fraction (303,402) in a cracking unit (300,400); and processing the second residuum fraction to DCU gas oil/lighter fraction (501) in a coking unit (500); and steam cracking at least one of the gas fraction (101), liquid fraction (102), CU gas fraction (301,401), and DCU gas oil/lighter fraction (501) to the hydrocarbon products (920).
