SHANGHAI, Oct. 29, 2026 /PRNewswire/ — 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.

**Three Projects, Three Distinct Milestones**

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.

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.

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.

**Why Devolatilization Matters**

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.

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.
