Patent ID: 10676681

Abstract:
The present invention relates to an integrated process to convert crude oil into petrochemical products comprising crude oil distillation, hydrocracking and olefins synthesis, which process comprises subjecting a hydrocracker feed to hydrocracking to produce LPG and BTX and subjecting the LPG 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 hydrocracker comprising an inlet for a hydrocracker feed, an outlet for LPG and an outlet for BTX; and a unit for olefins synthesis comprising an inlet for LPG produced by the integrated petrochemical process installation and an outlet for olefins. The hydrocracker feed used in the process and the process installation of the present invention comprises one or more of naphtha, kerosene and gasoil produced by crude oil distillation in the process; and refinery unit-derived light-distillate and/or refinery unit-derived middle-distillate produced in the process. The process and process installation of the present invention have an increased production of petrochemicals at the expense of the production of fuels and an improved carbon efficiency in terms of the conversion of crude oils into petrochemicals.
