Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! On January 2, 2019, the thermohigh-pressure separator was successfully lifted and installed on site, marking a new phase in the construction of Sinopec Maoming Branch’s product structure optimization project. The thermal high-pressure separator is the core equipment of Sinopec Maoming Branch’s 2.6 million tons per year slurry-bed residue hydrocracking and light oil hydrogenation complex; it has an inner diameter of φ4500 mm, a total length of 21,687 mm, and a wall thickness of 261 mm + 8 mm. The weight of each unit is 617 tons, and the material used is 2.25Cr-1Mo-0.25V (with double-layer cladding: TP.309L + TP.347). Due to transportation constraints, the equipment for this unit was prefabricated in sections at China National Heavy Machinery Corporation’s Deyang facility, with the final assembly being carried out at the Maoshan Petrochemical project site. Throughout the entire manufacturing process, Nanjing Sanchang maintained strict quality control, and actively coordinated with Sinopec’s Materials and Equipment Department, the users of Sinopec’s Maoming branch, as well as China National Heavy Machinery Corporation. Through the joint efforts of all parties, this equipment was accepted by the user side on January 2, 2019, and successfully installed; the whole process took nearly 13 months.
