DODGEN Reports Industrial Milestones for POE Devolatilization Projects in China

Engineering firm DODGEN has announced key operational and contractual milestones across three industrial polyolefin elastomer (POE) projects in China throughout 2026. The updates span successful facility start-ups at CNPC Daqing Petrochemical and Xingchuan New Materials, alongside a supply contract agreement with Shaanxi Yuneng.

Project Milestones and Operational Progress

The reported developments involve distinct stages of project delivery and execution:

• CNPC Daqing Petrochemical: The company's 30,000-tonne-per-year industrial demonstration plant completed its full process flow on September 23, 2026, and successfully produced on-specification product on September 26 on its first attempt. DODGEN engineered and supplied proprietary core equipment for this facility's devolatilization section.
• Xingchuan New Materials: Operating a 10,000-tonne-scale hyperbranched POE (H-POE) plant, the company achieved a successful first-attempt start-up by producing on-specification products on September 12, 2026. DODGEN provided the complete process solution for the plant's polymer devolatilization unit utilizing its DSXL devolatilization platform.
• Shaanxi Yuneng Energy and Chemical New Materials: On May 21, 2026, DODGEN signed an agreement with the company—a wholly owned subsidiary of Yulin Energy Group—to supply a devolatilizer system for a planned 100,000-tonne-per-year POE unit located in the Shenmu High-Tech Industrial Development Zone. This system is designed to eliminate volatile impurities such as heptane solvent and ethylene.

Understanding Polymer Devolatilization

Following solution polymerization, polymer solutions and melts retain solvents, unreacted monomers, and other volatile components. Effectively removing these elements to meet stringent product specifications requires managing technical challenges including high fluid viscosity, heat-transfer limitations, narrow temperature windows, and continuous operational demands.

Devolatilization performance directly influences residual chemical levels, molecular-structure preservation, pelletizing stability, batch-to-batch consistency, and overall energy consumption. DODGEN's DSXL technology platform addresses these requirements by integrating high-efficiency heat transfer for viscous fluids, static mixing, uniform melt distribution, and multi-stage flash and vacuum devolatilization.

Practical Implications and Verification

For industry observers and stakeholders, evaluating devolatilization systems requires analyzing several technical and operational variables:

• Confirmed Facts: Two industrial facilities (CNPC Daqing and Xingchuan New Materials) successfully produced on-specification POE products following plant start-ups in September 2026 utilizing DODGEN equipment or process solutions. Additionally, a formal supply contract was signed with Shaanxi Yuneng in May 2026.
• Unknowns and Future Progress: Subsequent operating progress and actual operational timelines for the Shaanxi Yuneng project remain pending and are slated for separate reporting as development advances.
• Evaluation Factors: Key metrics for similar systems include feed rheology, product-specific residual limits, testing methodologies, facility capacity, and system boundaries encompassing vacuum systems, condensation, solvent recovery, and pelletizing.
