Sinochem International's carbon three phase I project has made significant progress since 2022, and the main devices in the project have been completed and put into operation. Among them, the commissioning of the propane dehydrogenation (PDH) plant with an annual output of 600000 tons marks the completion of the project and the successful integration of the whole industrial chain of epoxy resin and other products. The commissioning of this important project will further consolidate Sinochem International's leading position in the domestic chemical industry.

Project situation

the project mainly produces phenol acetone, bisphenol A, epoxy chloropropane, epoxy resin and other fine chemical products. Among them, the annual output of 400000 tons of propylene oxide plant is one of the core of the project, which is expected to be put into operation on November 8, and qualified products are expected to be produced in early December. These products are widely used in industries such as pharmaceuticals, pesticides and dyes, as well as new materials, new energy and other traditional businesses.

Company situation

after years of strategic transformation, Sinochem International has successfully transformed into an international enterprise group with fine chemical production as its main business. The company has acquired a large number of high-quality assets through investment and mergers and acquisitions, including mergers and acquisitions holding companies such as Shengao Chemical, Yangnong Group, Elix Polymers, etc., laying a good foundation for the smooth realization of industrialization transformation. Sinochem International's business scope covers chemical intermediates, polymer additives, new materials, new energy and other traditional businesses. Through complementary advantages among industries and relying on the green circular economy industrial chain, Sinochem International has realized the continuous derivation of product chains and the efficient utilization of resources to form core competitiveness.. The company's products mainly include chlorobenzene series and nitrochlorobenzene series, which are widely used in pharmaceutical, pesticide and dyestuff industries. In the field of new materials, the company mainly produces high-performance fiber materials such as aramid and high-strength polyethylene, as well as materials such as epichlorohydrin and epoxy resin, which are used in coatings, electronic and electrical industries. In addition, the company also produces lightweight materials such as PU, PC, PS and ABS.

With the increasingly strict environmental protection policy, the traditional chlorohydrin process is gradually eliminated, and the direct oxidation process has attracted much attention because of its environmental protection and pollution-free advantages. Sinochem International adopts the direct oxidation method to prepare propylene oxide, and its scale and technology are in the leading position in China. In the future, with the continuous strengthening of national environmental protection policies and the development of new technologies, the direct oxidation process will be more widely used, and the requirements for product quality will continue to increase. While expanding its production scale, Sinochem International will continue to optimize processes and technologies, improve product quality and reduce costs to maintain its competitive advantage.

New Point of Demand for Propylene Oxide

dimethyl carbonate (DMC) is a kind of product with low toxicity and excellent environmental performance. In the context of green chemistry, new energy promotion and sustainable development, dimethyl carbonate (DMC) is widely used in the industrial field. In addition to traditional adhesives, coatings and developers, lithium battery electrolyte solvents have accounted for 30% of DMC downstream applications in recent years, becoming the main application area of this product. In terms of product purity, the lower purity of industrial-grade dimethyl carbonate is mainly used in traditional downstream and polycarbonate (PC), while lithium battery electrolytes require higher purity battery-grade dimethyl carbonate. At present, the main suppliers of battery-grade DMC are Shi Dasheng Hua (75000 tons/year), Oak shares (20000 tons/year) and so on. In the future, companies that will enter this market include Xinzhoubang, Sinochem Quanzhou, Zhejiang Petrochemical, Hualu Hengsheng, etc. In the next 3-5 years, the new project capacity of domestic carbonate series products will exceed 4 million tons/year, which will bring new demand for propylene oxide market.
