USEON Successfully Commissions a 30,000 Tons/Year POE Production Plant
USEON, a leading manufacturer of twin-screw extrusion and polymer processing technologies, has played a key role in the successful commissioning of Daqing Petrochemical's polyolefin elastomer (POE) production plant in China, with an annual capacity of 30,000 tons.
The project, implemented within the PetroChina Group, represents a significant technological achievement in the industrial production of high-value-added polymers. USEON designed and manufactured the large-scale devolatilization, extrusion, and pelletizing systems used in the facility.
Successful Commissioning and First Production
As part of the plant investment initiated in July 2025, USEON undertook the engineering and manufacturing of the high-capacity twin-screw extrusion and pelletizing system.
The initial system tests were successfully completed on July 25, 2026. Subsequently, on September 23, 2026, the complete production process was commissioned, and the first POE pellets were successfully produced.
Quality inspections conducted on September 26, 2026, confirmed that the produced material met the required product specifications.
This achievement marked the first industrial-scale application of PetroChina's independently developed solution-based POE production technology.
Advanced High-Capacity Devolatilization Technology
One of the most important technological components of the project is the large-scale continuous devolatilization system developed by USEON.
POE produced through solution polymerization requires specialized processing technologies due to its high solvent content and viscosity. Effective solvent removal, precise melt flow control, and consistent pellet quality are critical factors in the production process.
At the heart of the system is a high-capacity twin-screw devolatilization extruder designed and manufactured by USEON.
The complete production system incorporates the following technologies:
Twin-screw devolatilization extruder
Melt gear pump
Melt filtration and screen changing system
Underwater pelletizing system
Thermal oil and cooling systems
Side extruder and auxiliary feeding systems
Stripping agent and additive dosing systems
Antioxidant dosing system
Vacuum solvent condensation and recovery system
The integrated operation of these components enables continuous processing of polymers containing high levels of solvent and reliable pellet production on an industrial scale.
What Is POE and Where Is It Used?
Polyolefin elastomers (POE) are high-performance polymer materials characterized by their flexibility, impact resistance, and excellent low-temperature properties.
POE materials are widely used in automotive, packaging, polymer modification, compounding, and solar energy applications.
Commonly used to improve the mechanical properties of polymers such as polypropylene and polyethylene, POE offers significant advantages in applications requiring enhanced impact resistance and flexibility.
With continuous advancements in production technologies, POE is becoming increasingly important in the high-value-added polymer market.
USEON's Expertise in Large-Scale Petrochemical Projects
The Daqing Petrochemical project is not USEON's first involvement in large-scale POE production facilities.
The company has previously participated in Sinopec's 50,000 tons/year POE plant and PetroChina's 100,000 tons/year POE project.
These projects, covering different production capacities, demonstrate USEON's extensive engineering expertise in processing high-viscosity polymers, solvent removal, melt filtration, and pelletizing technologies.
In high-capacity petrochemical applications requiring continuous and reliable production, integrated process engineering and the seamless operation of all system components are essential.
USEON continues to apply its expertise to the development of next-generation polymer production technologies.
