In-Line Moisture Determination in a Fluid Bed Dryer Using NIR

For many applications in industry, the fluid bed granulator/dryer is an integral point in the manufacture of materials. Residual moisture must be kept within certain specifications to avoid fracturing of particles or caking (stickiness) of the bulk material. Current methods are slow and cumbersome, which can lead to damaged or degraded products. The ability to monitor the residual moisture content in-line is possible with near-infrared (NIR) spectroscopy which can improve the process efficiency, yield, and overall product quality.

In this webinar, Yusuf Sulub, Analytical Science Manager at SABIC, and Andrew Tatsch present a robust real-time, in-line determination of high rubber graft (HRG) acrylonitrile butadiene styrene (ABS) resin moisture levels in a fluid bed dryer (FBD). They also discuss how you can combine chemometrics and NIR spectroscopy to determine the moisture levels of HRG powders and explore how the calibration dataset was acquired from both offline and in-line FBD data to include dynamic process information.
