Systems and processes for direct crude oil upgrading to hydrogen and chemicals

A system for hydrocarbon separation and upgrading, the system comprising:

• an inlet hydrocarbon stream;
• a feed inlet splitter operable to separate the inlet hydrocarbon stream into a light fraction comprising naphtha boiling point temperature range material and a heavy fraction comprising diesel boiling point temperature range material;
• a hydrogen production unit operable to produce from the light fraction syngas comprising H2 and CO;
• a carbon reaction unit operable to react the CO produced from the light fraction via at least one reaction selected from the group consisting of:
• carbonylation, polymerization, and water-gas shift;
• a high-severity fluidized catalytic cracking (HS-FCC) unit operable to produce from the heavy fraction CO2, polymer grade ethylene, polymer grade propylene, C4 compounds, cracking products comprising naphtha boiling point temperature range products with olefins and aromatics, light cycle oils, and heavy cycle oils;
• a CO2 collection and processing unit operable to collect and purifying the CO2 produced from the heavy fraction;
• an oligomerization unit operable to process the C4 compounds to produce olefinic oligomerate and paraffinic raffinate, the paraffinic raffinate being used to produce hydrogen in the hydrogen production unit;
• a cracked naphtha splitter operable to separate the cracking products comprising naphtha boiling point temperature range products with olefins and aromatics into a light cut naphtha stream including C5 and C6 olefins and an aromatic stream comprising aromatic compounds, wherein the oligomerization unit is operable to oligomerize the light cut naphtha stream;
• a heavy naphtha selective hydrotreating unit operable to hydrotreat the aromatic stream;
• a cycle oils hydrocracker unit operable to hydrocrack the light cycle oils to produce a monoaromatics product stream;
• a gasifier unit operable to gasify the heavy cycle oils to produce hydrogen, CO, and CO2, wherein the carbon reaction unit is operable to react the CO produced from gasifying the heavy cycle oils via at least one reaction selected from the group consisting of:
• carbonylation, polymerization, and water-gas shift, wherein the CO2 collection and processing unit is operable to collect and purifying the CO2 produced from gasifying the heavy cycle oils;
• and
• an aromatic extraction unit operable to process and separate produced aromatic compounds into benzene and para-xylene.
