🔑 Enhanced Key Takeaways
- •The 2.4 million-ton coal-to-ethylene glycol project is situated in Xinjiang's Turpan Economic Development Zone and is recognized as the world's largest single high-quality fiber coal-to-ethylene glycol facility currently under construction.
- •The project will utilize brown coal sourced from the Aiding Lake mining area in Turpan as its primary raw material and will implement Shanghai Pujing Chemical's advanced gasification and synthesis gas to ethylene glycol technology.
- •Beyond its main product, the facility is designed for resource cascade utilization, producing high value-added by-products such as dimethyl carbonate (DMC), coal-based ethanol, sulfur, and liquid ammonia.
- •This strategic investment aims to establish a vertically integrated industrial cluster, creating a comprehensive supply chain that extends from coal to polyester new materials and textiles.
🛠️ Technical Deep Dive
- The project employs internationally advanced gasification and synthesis gas to ethylene glycol technology routes, specifically utilizing Shanghai Pujing Chemical's complete process technology and specialized catalysts.
- The coal-to-ethylene glycol process typically involves producing ethylene glycol from coal-based syngas via dimethyl oxalate (DMO) as an intermediate.
- This DMO route includes oxidative carbonylation to produce DMO, followed by hydrogenation to yield ethylene glycol (EG).
- Critical aspects of the process include stringent purity and quality control, particularly for aldehyde content and ultraviolet transmittance, to ensure polyester-grade ethylene glycol.
- Unlike petroleum-based processes, coal-to-ethylene glycol requires specialized refining processes due to distinct reaction mechanisms and impurity profiles.
- The facility incorporates low-carbon circular systems, including green electricity coupling and carbon capture and storage (CCS) technologies.
