Looking at the ten years of development of chemical technology, we praise the prosperity and strength of China in the prosperous age. It is more lively and more exciting with everyone's participation. [Ten Years of Development of Chemical Equipment] Continue to update summary posts, welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Enhance quality awareness and promote high-quality development-----------------------------------------On October 12, 2023, the construction of the 300,000-ton-per-year polystyrene unit of the Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project officially started. 　　The device adopts the second-generation polystyrene proprietary technology independently developed by Guangdong Huanqiu Guangye Engineering Co., Ltd., a subsidiary of China Huanqiu Engineering Co., Ltd., and mainly includes process units such as batching, polymerization, devolatilization, vacuum, granulation and hot oil, as well as auxiliary facilities such as public works. The device has one general-purpose polystyrene (GPPS) product production line and two impact-grade polystyrene (HIPS) product production lines, with a single-line production capacity of 100,000 tons per year. Product lines can be switched between each other for production, and the operational flexibility is 60%~110%. 　　The device is designed and constructed by Guangdong Huanqiu Guangye Engineering Co., Ltd. and is expected to be delivered on March 30, 2025. The commissioning of the device will further improve the product chain and balance the supply of styrene raw materials, which is of great significance to the overall implementation of the integrated refining and chemical transformation and upgrading project.
