High-cycle valves for polymerization
The function of valves in polymerization reactors varies, depending on the process stage. They can be used for product conveyance, isolation, gas venting or pressure balancing. But all these applications call for reliable, high-cycle valve operation.
Polymerization calls for robust valve performance − from 100,000 up to 1,500,000 cycles per year, with a stroke time of less than three seconds. Also, the process involves high pressure differences and vibration-affecting devices. And mediums often contain abrasive elements, while continuous polymerization can lead to polymer growth in valve parts.
A metal-seated ball valve design with long-lasting tightness and cycle life is critical for this type of application. Polymer-proofing is a must if you want to make sure polymers do not penetrate behind the seat, seizing your valves. Also abrasion caused by a catalyst can be a problem for valves. This must be taken into account when selecting the suitable valve type.
Valves must be equipped with instrumentation according to site-specific conditions. Plus, diagnostic capabilities allow proactive maintenance planning and valve condition monitoring.
