Give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On December 30, 2024, the handover ceremony for Sinopec’s world’s largest high-performance polypropylene (PP) production facility, with an annual output of 1.5 million tons, was held in the Jiangyin Port City Economic Zone in Fuzhou. This marked the completion of the installation and acceptance processes for this facility, which has now entered the pre-commissioning phase. “Covering an area of 60 mu, the project has a total investment of 3.8 billion yuan, with an annual output value of 15 billion yuan. It drives an additional output value of 30 billion yuan across related industries in the supply chain, making it the largest single high-performance polypropylene production facility in the world today. ”Weng Shengjin, member of the board of directors of Fujian Zhongjing Petrochemical Group, said. It is understood that the project took more than 18 months, from installation in June 2023 to the completion and acceptance by CCCC, during which numerous technical challenges were overcome in the stages of engineering design, construction, and installation. Compared with similar devices, this project has the largest scale, the greatest amount of work involved, and the smallest land area required. “This high-performance polypropylene production line utilizes a fully domestic process with independent intellectual property rights – a combination of vertical tank slurry polymerization and horizontal tank gas-phase polymerization technologies. It features 3 production lines for manufacturing homopolymer or random copolymer polypropylene powder, and boasts significant advantages such as high efficiency, low energy consumption, and environmental friendliness. The project also includes a horizontal tank reactor with a capacity of 80 cubic meters, the largest of its kind in the country; its mechanical seal with a diameter of 310 millimeters is also the largest of its kind in the industry. The construction of this facility will play an important role in extending, complementing, and strengthening the company’s carbon triolefin industry chain. ”Huang Min, deputy general manager of Zhongjing Petrochemical, said. It is reported that once the project is put into operation, it will supply high-quality raw materials for various industries such as modified plastics, medical supplies, engineering plastics, melt-blown fabrics, auto parts, non-woven fabrics, packaging materials, and building materials, thereby filling the gap in the production of high-performance polypropylene in South China. It is understood that the Zhongjing Petrochemical Technology Park is the only enterprise in the world today that possesses a complete industrial chain ranging from \"port storage to propane, propylene, polypropylene, and polypropylene films\". It connects ports, energy, the chemical industry, plastics, and the flexible packaging sector together, creating an efficient integrated ecosystem. The Zhongjing Petrochemical Technology Park will be developed in phases; once fully operational, it will become the world’s largest facility for producing propylene via propane dehydrogenation, with an annual output of 3.8 million tons, as well as the world’s largest single-site plant for polypropylene production, with an annual output of 4 million tons.
