Abstract
The present invention relates to an integrated process to convert crude oil into petrochemical products comprising crude oil distillation, dearomatization, ring opening, and olefins synthesis, which process comprises subjecting a hydrocarbon feed to dearomatization to produce a first stream enriched in aromatic hydrocarbons and naphthenic hydrocarbons and a second stream enriched in alkanes; subjecting a stream enriched in aromatic hydrocarbons and naphthenic hydrocarbons to ring opening to produce alkanes; and subjecting refinery unit-derived alkanes produced in the process to olefins synthesis. Furthermore, the present invention relates to a process installation to convert crude oil into petrochemical products comprising a crude distillation unit comprising an inlet for crude oil and at least one outlet for one or more of naphtha, kerosene and gasoil; a dearomatization unit comprising an inlet for a hydrocarbon feed to dearomatization, an outlet for a stream enriched in aromatic hydrocarbons and naphthenic hydrocarbons and a second stream enriched in alkanes; a ring opening unit comprising an inlet for aromatics and naphthenes produced by dearomatization and an outlet for alkanes…
