Abstract:
A method of controlling the supply and allocation of hydrogen gas in a hydrogen system of a refinery integrated with olefins and aromatics plants to convert crude oil into petrochemicals. The method includes one or more supply sources that provide hydrogen at individual rates, purities, pressures and costs, multiple consumption sites that consume hydrogen at individual rates, purities and pressures and an interconnecting hydrogen distribution network. The method further includes the integration of hydrogen consuming process units with hydrogen producing process units in which hydrogen recovered from the effluents from the hydrogen consuming process units and hydrogen recovered from the hydrogen producing process units are re-used in the hydrogen consuming process units.

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.
Abstract:
An integrated process to convert crude oil into petrochemical products includes distilling crude oil to produce gases fraction, naphtha, kerosene, gasoil and resid; subjecting resid to resid upgrading to produce LPG, light-distillate and middle-distillate; subjecting at least a portion of one or more of the group consisting of middle-distillate produced by resid upgrading, kerosene and gasoil to middle-distillate hydrocracking to produce LPG, light-distillate and hydrowax; and subjecting at least a portion of one or more of the group consisting of light-distillate produced by resid upgrading, light-distillate produced by middle-distillate hydrocracking and hydrowax to steam cracking. A process installation for performing the process is also provided.
Abstract:
The present invention relates to a process for converting a high-boiling hydrocarbon feedstock into lighter boiling hydrocarbon products, said lighter boiling hydrocarbon products being suitable as a feedstock for petrochemicals processes, said converting process comprising the following steps of: feeding a hydrocarbon feedstock having a boiling point of >350 deg Celsius to a cascade of hydrocracking unit(s), feeding the bottom stream of a hydrocracking unit as a feedstock for a subsequent hydrocracking unit, wherein the process conditions in each hydrocracking unit(s) are different from each other, in which the hydrocracking conditions from the first to the subsequent hydrocracking unit(s) increase from least severe to most severe, and processing the lighter boiling hydrocarbon products from each hydrocracking unit(s) as a feedstock for one or more petrochemicals processes.
Abstract:
The present invention relates to a process for cracking a hydrocarbon feedstock in a steam cracker unit, comprising the following steps of: feeding a liquid hydrocarbon feedstock to a hydrocracking unit, separating the stream thus hydrocracked in said hydrocracking unit into a high content aromatics stream and a gaseous stream comprising C2-C4 paraffins, hydrogen and methane, separating C2-C4 paraffins from said gaseous stream, feeding said C2-C4 paraffins thus separated to the furnace section of a steam cracker unit.
