Core Viewpoint - The Guangxi Petrochemical Integration Project has successfully transitioned from a "fuel-type" to a "chemical material-type" operation with the commissioning of China's first epoxy propylene-styrene (POSM) co-production unit, marking a significant milestone in the industry [1]. Group 1: Project Overview - The POSM unit is a critical component of the petrochemical chain, featuring 35 towers, 21 reactors, and over 400 rotating devices, covering an area larger than that of an ethylene unit [2]. - The project was completed in 24 months, setting a new domestic record for similar installations, with a full process integration achieved in just 48 hours [1][2]. Group 2: Technical Challenges and Solutions - The waste alkali incinerator posed significant operational challenges, often leading to reduced efficiency in similar domestic units [2]. - A dedicated technical research team conducted in-depth investigations into existing units that faced issues, transforming identified risks into stringent technical requirements for suppliers [2]. Group 3: Engineering Innovations - The project team implemented an "surgical" optimization plan for the installation of two large oxidation reactors, which are crucial for the unit's operation, allowing for better space management and time savings [4][5]. - The transportation of these reactors faced logistical challenges, including low water levels and adverse weather, but the team successfully coordinated efforts to ensure timely delivery [5]. Group 4: Team Dynamics and Performance - The project was executed by a young and resilient team of fewer than 20 core members, all with 10 to 15 years of experience, emphasizing a collaborative problem-solving approach [7]. - The team managed to adapt to significant design changes during peak periods, demonstrating flexibility and commitment to project goals [7]. Group 5: Operational Success - The POSM unit has been in stable operation for over two months, producing high-quality products that meet leading domestic performance indicators [7]. - The project is now recognized as an industry benchmark not only for construction speed but also for operational efficiency, environmental performance, and product quality [7].
