【Ten Years of Great Progress in Chemical Technology】The world’s largest propane dehydrogenation to propylene plant, 281-2023, has completed installation and acceptance
Thread Content
Looking at the ten-year development of chemical technology, we praise the prosperity and strength of modern China. This is just a starting point to encourage further discussion among everyone; with your participation, things will become even more interesting. [Ten Years of Progress in Chemical Equipment] – continuous updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Prevention first, life above all. ----------------------------------------- On October 31, 2023, the groundbreaking ceremony for the second phase of Zhongjing Petrochemical’s project, which has an annual production capacity of 1 million tons of propylene dehydrogenation products, was held at the Zhongjing Petrochemical Technology Park in Jiangyin, Fuqing, Fujian. This landmark event marks the completion of the installation and commissioning of the world’s largest propane dehydrogenation to propylene plant, and it also indicates that the project is about to enter the pre-commissioning phase, laying a solid foundation for its official operation next month. It is understood that the second phase of Zhongjing Petrochemical’s project, which has an annual production capacity of 1 million tons of propylene dehydrogenation product, requires a total investment of 4 billion yuan. The annual output value is expected to reach 10 billion yuan, while it will also drive an additional 20 billion yuan in output value for the downstream industries. This is currently the largest propane dehydrogenation to propylene plant in the world. The project incorporates the state-of-the-art propane dehydrogenation technology for propylene production from the American company Lums, with the aim of supplying high-purity propylene raw materials to downstream polypropylene manufacturers, thereby completing the internal circular industrial chain. Since the reactor of the propane dehydrogenation unit was lifted into place at the project site in September 2022, 13 months later, the project has successfully set several world records. Among them, the propane-propylene separation tower is the most critical equipment in this plant. With a height of 138 meters and a volume of 11,000 cubic meters, it is the tallest and largest propane-propylene separation tower in the world today.
The domestic production rate for all components of this device has reached 99%. ”A relevant official from Zhongjing Petrochemical said. During the project’s phases of technology introduction, engineering design, equipment procurement, construction, and installation, Zhongjing Petrochemical worked closely with well-known domestic enterprises and research institutions to overcome numerous technical challenges; in particular, it achieved the first domestic production of 50MW positive-pressure explosion-proof motors and 169MW air heaters. In response to the strategic goals of \"reaching carbon peak and achieving carbon neutrality,\" Zhongjing Petrochemical signed a contract with British company Sinopec this year to introduce the world’s most advanced BDO production technology, and to invest in projects related to the carbon tetrahydrocarbon industry chain (hydrogen utilization and related processes), thereby ensuring the recyclability and sustainable development of these projects. It is worth noting that once the second phase of Sinochem’s Zhongjing Petrochemical project, with an annual production capacity of 1 million tons of propane dehydrogenation product, comes online, in addition to producing 1 million tons of high-purity propylene per year, the project will also generate 50,000 tons of hydrogen as a by-product. This provides strong support for Zhongjing Petrochemical Group to strengthen and expand its C4 carbon chain industry. The total planned investment for the Fuzhou Jiangyin Zhongjing Petrochemical Technology Park project amounts to 50 billion yuan. It is the only BOPP enterprise in the world today that has established a complete industrial chain covering \"wharf storage – propane – propylene – polypropylene – polypropylene film\". The completion of the acceptance testing for the world’s largest propylene production facility via propane dehydrogenation will have a profound impact on the global propylene market. With the commissioning of this project, it is expected that the global supply of high-purity propylene raw materials will increase, further boosting the development of industries such as polypropylene. At the same time, the successful implementation of this project serves as a model for reference and learning for enterprises in other ** and regions, contributing to the upgrading and transformation of the global chemical industry.

The propane-propylene separation tower is 138 meters tall; I wonder what its weight is? Installation is a challenge, and it’s worth praising.
