PAPER STRENGTH OPTIMIZATION UTILIZING DATA ANALYTIC MEASUREMENT AND CONTROL, TAPPICon22
Paper machine quality control systems leverage a wide array of regulatory (‘level 1’) and supervisory (‘level 2’) controls to maintain various process variables and key quality parameters at their desirable setpoints. Intelligent optimization (‘level 3’) based on data analytics combines process control with quality and cost data (e.g. sheet strength and fiber cost) to bring machine performance and efficiency to the next level.
Sheet strength measures are critical quality properties that greatly affect the salability and usefulness of paper. Controlling sheet strength is challenging due to the relatively low frequency of laboratory measurements, usually once per reel. Unlike other quality properties such as weight or moisture, strength measurement requires destructive testing that cannot be performed with a physical on-machine sensor.
