METHOD AND INSTALLATION FOR CONVERSION OF RAW OIL IN PETROCHEMICAL PRODUCTS WITH INCREASED PROFILE OUTPUT

摘要

The present invention relates to a combined method for converting crude oil into petrochemical products, in which crude oil is distilled, the aromatic ring is opened and olefins are synthesized, and this method includes the steps in which the hydrocarbon raw material is opened to open the aromatic ring to form LPG and subjected to LPG, formed in the combined method, the synthesis of olefins. In addition, the present invention relates to a process plant for converting crude oil to petrochemical products, comprising a crude oil distillation unit, comprising an input for crude oil and at least one output for kerosene and / or gas oil; installation of the opening of the aromatic ring containing input for hydrocarbons supplied to the opening of the aromatic ring, and output for LPG; and a plant for the synthesis of olefins, containing input for LPG formed by a combined petrochemical process plant, and output for olefins. The hydrocarbon feedstock subjected to the opening of the aromatic ring contains kerosene and / or gas oil, obtained by distilling crude oil in the specified method, and the middle distillate formed by the refining facility, obtained in the specified method. The method and technological installation of the present invention have an increased formation of petrochemical products due to the formation of fuels and an increased yield of propylene.
