DODGEN Reports Devolatilization Start-Ups at Two Chinese POE Plants and Signs a Third Supply Contract
The third project has so far produced only a contract.
Mark
Why would a company announce a component supplier's role in a plant start-up?
Mimi
Because devolatilization is the step that decides whether the product meets spec. DODGEN is saying its equipment sat at that point in two plants that hit on-spec product first time.
Mark
What exactly does the equipment do?
Mimi
After polymerization the material still holds solvent and unreacted monomer. The system strips those out to product-specific limits, working with very viscous material and narrow temperature windows.
Luke
Before we go further, who is telling us all this? The release is DODGEN's own.
Mimi
Yes. The Daqing dates, September 23 and 26, come from the release itself. The Xingchuan date of September 12 is attributed to that company's announcement.
Luke
So no independent confirmation of either start-up. And "successful first-attempt" is a characterization, not a measured result.
Mark
What about the third project?
Mimi
Shaanxi Yuneng signed on May 21 for a devolatilizer system for a planned 100,000-tonne-per-year unit. Nothing is running there.
Luke
Right, and the release says so. It's a contract, not an outcome. We also have no contract value, no delivery date and no start-up timeline.
Mark
So what should a reader watch for?
Mimi
Third-party or customer confirmation of the start-ups, and commissioning news from Shenmu when it comes.
Le Pouls
- Two POE plants, at CNPC Daqing and Xingchuan New Materials, claim first-attempt start-ups with on-specification product in September 2026.
- The devolatilization step, which must pull solvent and volatiles out of a thick, heat-sensitive polymer, is where production quality is won or lost.
- A third 100,000-tonne unit at Shaanxi Yuneng signed its equipment contract in May, but it has not been built and carries no operating record yet.
- All the start-up claims come from the vendor's own promotional release, so the story is still waiting for independent confirmation.
- The next signals to watch are outside verification of the Daqing and Xingchuan results and commissioning news from Shaanxi Yuneng.
In late September 2026, two Chinese plants making polyolefin elastomer, a rubbery plastic used in cables, packaging and auto parts, reportedly began production on their first attempt, and a third plant signed up for equipment that will someday do the same. The account comes from DODGEN, a Shanghai process-technology firm that supplied the critical step of stripping leftover solvent and unreacted material from the molten polymer. Like many industrial milestones, it is a story told first by the party that built the machinery, so its meaning will rest on whether neutral observers later confirm what the vendor has described.
On September 23, the 30,000-tonne demonstration plant at CNPC Daqing Petrochemical ran its full process flow for the first time. Three days later, on September 26, it made product that met specification. Those are the dates given by DODGEN, a Shanghai company specializing in process intensification and separation, in a release issued on October 28, 2026.
The release covers three Chinese polyolefin elastomer (POE) projects that DODGEN says it equipped with devolatilization technology this year. Two have started up. The third has so far produced only a signed contract. At Daqing, DODGEN says it engineered and supplied the proprietary core equipment for the devolatilization section.
At Xingchuan New Materials, a hyperbranched POE plant of about 10,000 tonnes, the company reports first on-specification output on September 12, again on the first attempt, citing its own announcement. DODGEN says it provided the complete process solution for the polymer devolatilization unit, built on its DSXL platform.
The third project is still ahead. On May 21, DODGEN agreed to supply the devolatilizer for a planned 100,000-tonne POE unit at Shaanxi Yuneng, a subsidiary of Yulin Energy Group, in the Shenmu High-Tech Industrial Development Zone. The system is meant to strip heptane, ethylene and other volatile impurities. The company says operating news will come separately.
The release explains why this step is hard. After solution polymerization, the polymer still holds solvents and unreacted monomers. Removing them means working with high viscosity, poor heat transfer and narrow temperature windows, while running continuously. That stage shapes residual levels, molecular structure, pelletizing stability and energy use.
The release is promotional and comes from the vendor. The Daqing dates are DODGEN's own, and the Xingchuan dates come from that company's announcement. Independent confirmation of the start-ups, and commissioning updates from Shaanxi Yuneng, are what will settle the story.
On September 23, the 30,000-tonne-per-year industrial demonstration plant at CNPC Daqing Petrochemical ran its full process flow from start to finish. Three days later, on September 26, it produced on-specification product. That is the account given by DODGEN, a Shanghai-based process technology company, in a release distributed on October 28, 2026, which describes the start-up as successful on the first attempt.
The release covers three Chinese polyolefin elastomer (POE) projects that DODGEN says it supplied with devolatilization technology in 2026. Two have started up. The third has so far produced only a contract. DODGEN engineered and supplied what it calls proprietary core equipment for the devolatilization section at Daqing.
The second start-up is at Xingchuan New Materials, which runs a hyperbranched POE plant (H-POE) at a scale of about 10,000 tonnes. According to the company's own announcement, as cited in the release, the plant produced its first on-specification products on September 12, also on a first attempt. DODGEN says it provided the complete process solution for the polymer devolatilization unit, built on its DSXL devolatilization platform.
The third project is further from production. 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. DODGEN will supply the devolatilizer system for a planned 100,000-tonne-per-year POE unit. The system is designed to strip heptane solvent, ethylene and other volatile impurities from the product. The unit is part of Phase I of the customer's epoxy-resin integration project in the Shenmu High-Tech Industrial Development Zone. DODGEN stresses that this is a contract milestone only and says later operating progress will be reported separately.
The release also explains why this step matters. After solution polymerization, the polymer solution or melt still carries solvents, unreacted monomers and other volatile components. Bringing those down to product-specific residual limits means dealing with high viscosity, limited heat transfer, narrow temperature windows and continuous operation. DODGEN says devolatilization bears directly on residual levels, preservation of molecular structure, pelletizing stability, batch consistency and energy use.
The DSXL platform, as described, combines heat transfer designed for viscous fluids, static mixing, uniform melt distribution, and single- or multi-stage flash and vacuum devolatilization. The company lists the factors it weighs in evaluating a project: feed rheology; product-specific residual limits and test methods; capacity, operating flexibility and downstream constraints; and the system boundary, which covers vacuum, condensation, solvent recovery, melt discharge and pelletizing.
DODGEN is headquartered in Shanghai and specializes in process intensification and separation. It says its engineering team has more than 20 years of experience in reaction and separation engineering, and that its technologies serve new-energy materials, biodegradable plastics, bio-based chemicals and fine chemicals.
The release is promotional and comes from the vendor. The Daqing dates are DODGEN's own, and the Xingchuan dates are attributed to that company's announcement. The Shaanxi Yuneng unit has not been built. Independent confirmation of the start-ups, and commissioning updates from Shaanxi Yuneng, are what to watch for next.
