A New Acoustic Sensing Technology for Optimizing Polyolefin Production. GranuMet XP polymer combines the powerful performance of GranuMet XP with a high number of acoustic emission channels. GranuMet XP polymer™ reduces production cost by detecting process upsets early. GranuMet XP polymer can be used in all particulate processing applications.
The size, hardness and flow parameters of particulates affect the acoustic signal in predictable ways. Acoustic emission measurement provides real time information for process control. High temperature intrinsically safe sensors (Tamb = 190º C).
Intrinsically safe acoustic emission sensors, preamplifiers and cables
Signal conditioning unit (including IS barriers)
Multi-channel GranuMet XP acoustic emission monitoring system
GranuMet XP modeling and statistical process control software
applications
Early detection of agglomeration in fluid bed reactors (PE and PP production)
Detection of condensates in recycle loops (onset of condensation mode)
Detection of entrained powders in gas streams (cyclone efficiency, grid blockages)
Monitor fines production / control cyclone discharge more precisely
Performance of pneumatic transport lines (detects blockages)
features & benefits
features
benefits
real-time information
Can be integrated into closed loop control
Integrated pattern recognition software
Instantly detects process upsets
(e.g. unwanted agglomeration)
High sensitivity
Detects low levels of entrained or condensed material
Non-invasive application
Installation costs minimal, does not block or become contaminated with product
Up to 16 independent channels acoustic emission channels
Monitor the largest fluid bed reactors or several applications on the same plant for the lowest price per channel
Intrinsically safe equipment (EEx ia IIC T3/4)
Safe installation in hazardous areas, does not need purged or explosion proof enclosures (even zone 0)
