USEON has recently reached an important milestone in a devolatilization project for a major petrochemical company. The complete system has entered the pre-delivery testing stage and successfully completed a 24-hour continuous trial run at USEON’s facility.
The material used during the test contained more than 80% solvent, creating demanding operating conditions for gas-liquid separation, mass transfer efficiency, vacuum stability, and continuous material handling.
Throughout the 24-hour test, the system operated steadily with good coordination between the individual process units. Residual solvent content was consistently controlled below 0.25%. As operating conditions stabilized, the residual solvent level was further reduced to below 0.15%, equivalent to less than 1,500 ppm, toward the end of the trial.
The successful continuous run provides an initial verification of the system’s operating stability and devolatilization performance under high solvent-load conditions, and lays a solid foundation for equipment delivery and subsequent on-site commissioning.
Devolatilization in Polymer and Petrochemical Processing
Devolatilization is widely used in petrochemicals, polymer materials, engineering plastics, synthetic rubber, elastomers, adhesives, and fine chemicals. Typical applications include the removal of residual monomers, solvents, moisture, and other low-molecular-weight volatile components.
As requirements for material purity, odor control, residual monomer levels, and product consistency continue to increase, devolatilization has become an increasingly important part of the overall production process.
This is particularly true when processing high-viscosity, high-solids, or heat-sensitive materials, where mass transfer efficiency, precise temperature control, stable vacuum conditions, and reliable long-term operation can have a direct impact on both product quality and production efficiency.
Building on USEON’s Devolatilization Expertise
USEON continues to develop devolatilization technologies and core equipment around several key processing challenges, including efficient mass transfer, stable material conveying, vacuum devolatilization, and long-term continuous operation.
The company currently holds multiple invention patents related to devolatilization and has developed capabilities covering process design, key equipment development, manufacturing, system integration, and project implementation.
Depending on material viscosity, volatile composition, thermal sensitivity, required throughput, and target residual volatile levels, USEON can develop application-specific process configurations and provide customized devolatilization equipment and integrated system solutions, including dynamic devolatilization systems.
The successful 24-hour continuous factory trial for this major petrochemical project represents an important validation of both system stability and devolatilization performance. It also reflects USEON’s ongoing technical development in high-viscosity material processing and dynamic devolatilization equipment.
Looking ahead, continued growth in high-performance materials, green chemical processing, and high-quality polymer production is expected to place greater emphasis on low residual monomer levels, low solvent content, reduced odor, and stable continuous production.
Higher efficiency, continuous processing, lower energy consumption, and more precise process control will remain important directions for the development of devolatilization technology.
USEON will continue to advance its devolatilization processes and core equipment, accelerate the industrial application of patented technologies, and further improve devolatilization efficiency, operating stability, and adaptability to challenging materials. The goal is to provide reliable and efficient devolatilization equipment and system solutions for customers across the petrochemical and polymer industries.
