Playing a part in efficient polymerization
Modern polyolefin production processes are extremely efficient at producing large quantities of polymer with less capital investment. However, since polymerizations are highly exothermic reactions, efficient heat removal remains a key concern in polyolefin reactors.
Valves have a critical role in ensuring that the polymerization process is stable, flexible and controlled. Proper valve performance improves the accuracy of throughput and stable reactor temperature control. Reliability is also key for efficient cooling and avoiding unnecessary valve and piping costs.
The choice of valve type depends on the actual process in question and specific conditions within the application. Many applications within polyolefin flow control require custom-made, license-specific or engineered globe, gate, plug or butterfly valves for severe conditions, such as product discharge, flashing, cavitation and catalyst feed.
A modular approach makes valves both standard and custom-made. When the body, actuation and positioning are based on industry standards, the packing structure, seat type, trim coating or diagnostic capabilities can be custom-made to suit the application. This makes the valves reliable, economical and easy to service.
