SHANGHAI, Oct. 28, 2026 \/CNW\/ — DODGEN supplied devolatilization technology to three Chinese polyolefin elastomer (POE) projects in 2026: two successfully started up at CNPC Daqing Petrochemical and Xingchuan New Materials, while Shaanxi Yuneng signed a supply contract with DODGEN. The projects highlight the role of devolatilization in plant start-up, product consistency and operating performance.<\/p>\n
Three Projects, Three Distinct Milestones<\/p>\n
CNPC Daqing Petrochemical’s 30,000-tonne-per-year industrial demonstration plant completed its full process flow on September 23 and produced on-specification product on September 26, marking a successful first-attempt start-up. DODGEN engineered and supplied proprietary core equipment for the plant’s devolatilization section.<\/p>\n
Xingchuan New Materials’ 10,000-tonne-scale hyperbranched POE (H-POE) plant produced its first on-specification products on September 12, also achieving a successful first-attempt start-up, according to the company’s official announcement. DODGEN supplied the complete process solution for the plant’s polymer devolatilization unit, based on its DSXL devolatilization platform.<\/p>\n
On May 21, DODGEN signed an agreement with Shaanxi Yuneng Energy and Chemical New Materials Co., Ltd., a wholly owned subsidiary of Yulin Energy Group, to supply the devolatilizer system for a planned 100,000-tonne-per-year POE unit. The system is designed to remove heptane solvent, ethylene and other volatile impurities from the product. The POE unit forms part of Phase I of the customer’s epoxy-resin integration project in the Shenmu High-Tech Industrial Development Zone. This remains a contract milestone; subsequent operating progress will be reported separately.<\/p>\n
Why\u00a0Devolatilization Matters<\/p>\n
After solution polymerization, polymer solutions or melts still contain solvents, unreacted monomers and other volatile components. Removing these components to product-specific residual limits requires management of high viscosity, heat-transfer limitations, narrow temperature windows and continuous operation. Devolatilization directly affects residual levels, molecular-structure preservation, pelletizing stability, batch consistency and energy consumption.<\/p>\n
DODGEN’s DSXL platform combines high-efficiency heat transfer for viscous fluids, static mixing, uniform melt distribution, and single- or multi-stage flash and vacuum devolatilization. Key evaluation factors include feed rheology; product-specific residual limits and test methods; capacity, operating flexibility and downstream constraints; and the system boundary covering vacuum, condensation, solvent recovery, melt discharge and pelletizing.<\/p>\n
