The hardware facilities for Shengteng Chemical’s 500,000-ton aromatic compounds project have been fully completed, and the plant is set to enter the trial production phase in the near future. The off-site expansion project for Hebei Shengteng Chemical Co., Ltd., which aims to increase annual production by 500,000 tons of aromatic compounds, involves an investment of 2.03 billion yuan. It is considered a key project at the provincial level. The production capacity for benzene, toluene, and xylene amounts to 511,200 tons per year, while by-products include 565,000 tons per year of refined diesel, 62,000 tons per year of liquefied gas, 60,000 tons per year of petroleum ether, 100,000 tons per year of National V 92 gasoline, 90,400 tons per year of National V 95 gasoline, 14,300 tons per year of hydrogen, and 8,400 tons per year of sulfur. . Aromatic hydrocarbons are produced using a light oil reforming process, with an annual output of 800,000 tons. The aromatic hydrocarbons production in this project utilizes a light oil reforming process. The raw material, naphtha (part of which is produced by the diesel hydrogenation unit of this project, while most of the naphtha is purchased from the market), is processed through an 800,000-ton/year light oil reforming complex to produce intermediate products such as refined naphtha, as well as xylene products and extraction feedstocks. The extraction feedstocks are fed into the extraction system to yield benzene and toluene products. The hydrogen produced as a by-product of light oil reforming, after being purified through a PSA unit, is partially reused in the pretreatment section of the light oil reforming unit, another portion is used in the diesel hydrogenation unit, and the remaining amount is all supplied to the hydrogen pipeline network of Huabei Petrochemical Company. The gasoline blending components produced by the light oil reforming unit are blended together with purchased MTBE and alkylated gasoline in the tank farm to produce gasoline products that meet the National V standards. The feed diesel for the diesel hydrogenation unit is coker diesel and catalytic diesel purchased from the market, and after hydrogenation, diesel that meets National V standards is produced. All the dry gas generated by the project undergo desulfurization treatment; the desulfurized dry gas is then fed into the fuel gas network to supply the heating furnaces of the project’s facilities. The acidic water generated by hydrogenation and that produced by light oil reforming is fed into a sulfur recovery unit to recover sulfur. Sulfur products for delivery.
