According to reports on April 22, the 600,000-ton propylene oxide project of Sinochem Tianchen in Quanzhou has been completed and is ready for operation; however, production has not yet begun. The initial plan is to start trial operations in May. Tianchen’s 600,000-ton/year propylene oxide project: The first phase of this project, carried out by Sinochem Tianchen Quanzhou New Materials Co., Ltd., was officially launched on July 12, 2022. Civil engineering work was completed by November 30 of the same year, while the important milestone of lifting large-scale equipment was reached on May 19, 2023. The project was fully delivered on October 18, thus completing its construction tasks successfully. The 600,000 tons per year propylene oxide project is being constructed by Zhonghua Chem Tianchen Quanzhou New Materials Co., Ltd., a subsidiary controlled by China Tianchen Engineering Co., Ltd. The project covers an area of over 1,000 mu, with a total investment of 7.38 billion yuan; it is located in the Nanshan area of the Quangang Petrochemical Park. The total construction period for the project is 36 months, using the HPPO process. The annual production project is implemented in two phases: In Phase 1, a 1×300,000 tons/year propylene oxide plant using the hydrogen peroxide method, as well as 2×450,000 tons/year plants using 27.5% hydrogen peroxide (accompanied by a 1×450,000 tons/year concentration unit for 50% hydrogen peroxide) will be built. Meanwhile, auxiliary facilities such as storage tanks for raw materials and finished products, air separation and air compression units, cooling stations, loading/unloading platforms, circulating water systems, condensate purification systems, accident ponds, main substations and plant transformer stations, mechanical and electrical maintenance facilities, chemical storage areas, flares, incineration units, and sewage treatment plants will also be constructed ； In the second phase, a 1×300,000 tons/year propylene oxide plant using the hydrogen peroxide process, as well as 2×450,000 tons/year hydrogen peroxide plants (accompanied by a 1×450,000 tons/year 50% hydrogen peroxide concentration unit) will be constructed, along with supporting utility and environmental protection facilities.
