    摘要： A method of producing a purified mixed xylene comprising: introducing toluene and methanol to an alkylation reactor; reacting the toluene and the methanol in the alkylation reactor to form a hydrocarbon stream comprising a first mixed xylene, wherein the alkylation reactor comprises an alkylation catalyst; separating the hydrocarbon stream into a toluene stream and a separated C8+ stream; introducing the toluene stream to a transalkylation reactor with a transalkylation catalyst to produce a transalkylated stream comprising a second mixed xylene; adding the transalkylated stream to the hydrocarbon stream; and separating a C8 product stream comprising the purified mixed xylene from the separated C8+ stream.

    摘要： A process for the preparation of a chemical composition comprising an aromatic compound α in a concentration B by weight, based on the total weight of the chemical composition, comprising: a. providing the following reaction components: i. a chemical composition comprising the following: a) The aromatic compound α in a concentration A by weight based on the total weight of the chemical composition, and b) An olefin in an amount in an amount of about 50 to about 99.99 wt. %, based on the total weight of the chemical composition, and ii. An acid; and b. reacting the components to obtain the chemical composition comprising the aromatic compound α in a concentration B by weight based on the total weight of the chemical composition; wherein the concentration B is less than the concentration A.

    摘要： 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; a unit for olefins synthesis comprising an inlet for alkanes and an outlet for olefins. The hydrocarbon feed subjected to dearomatization 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 the process installation of the present invention have an increased production of petrochemicals at the expense of the production of fuels and an improved ethylene yield.

    摘要： An electronic bypass system can include receiving a request to bypass a plant interlock system. A review of the request can be facilitated by a computer and, based on input from at least one reviewer, results in the request being approved or not approved. The facilitating can include: notifying the at least one reviewer of the request, storing the request and a status of the request in a database that includes bypass statuses of a plurality of plant interlock systems, and prompting the at least one reviewer to respond based on not receiving input from the at least one reviewer within a specified review time period. Based on the result of the review, the status of the request can be updated in the database to approved or not approved. A report that includes the status of the request can be generated.
