Optimum Cost

Advanced process control technology can provide sugar processors the ability to realize major revenue enhancements and/or operating cost reductions with low initial investment. One technology in particular, model predictive control (MPC), holds the potential to increase production, reduce energy costs, and reduce quality variability in a wide variety of major sugar unit operations. These include centrifugal stations, pulp dryers, extractors, diffusers, mills, evaporating crystallizers, juice purification, and more. Simple payback periods as low as two months are projected. As a PC-based add-on to existing distributed control systems (DCS) or programmable logic controller (PLC) systems, MPC acts as a multi-input, multi-output controller, utilizing predictive process response models and optimization functions to control complex processes to their optimum cost and quality constraints.

Industrial Context

A process control course was elaborated around the specific regional (industrial) context in which UQAR has an important mission of regional development. A multidisciplinary approach is used, integrating notions from various fields of engineering (electrical, mechanical, chemical and civil engineering) through theme examples such as wastewater treatment, pulp and paper making, mining and metallurgical extraction (mineral grinding). Laboratory activities on such processes are realized using a simulation software specifically designed for process control education. The small size of the groups at UQAR also allows to employ innovative strategies on how to run the activities and to evaluate the students. One laboratory on a real physical system (electrical motor) was also part of the course, to balance between the advantages of the software and the more “hands-on” laboratories. General feedback and comparative appreciation from students is then presented, followed by overall conclusions
