Abstract: The present disclosure provides a system and method for converting crude oil to light hydrocarbon products useful as a chemical feedstock. The system may also include a conversion system, such as a steam cracking unit, that converts the chemical feedstock from the feed preparation system to useful hydrocarbon chemicals. Exemplary hydrocarbon chemicals produced by the conversion system include light olefins, such as ethylene, propylene, and/or butadiene.

Abstract: Method and apparatuses for producing ethylene and propylene from naphtha feedstock are provided. The naphtha feedstock includes a first component consisting of hydrocarbons that have less than or equal to five carbon atoms and a second component. The second component consists of at least one of an isoparaffin component having at least six carbon atoms, a naphthene component having at least six carbon atoms, or an aromatic component having at least six carbon atoms. The naphtha feedstock is separated to produce a first separation stream including the first component and a second separation stream including the second component. At least a portion of the second component from the second separation stream is converted to normal paraffins. Normal paraffins from conversion of the second component and at least a portion of the first component or derivative thereof from the first separation stream are steam cracked to produce ethylene and propylene.
