Within the Chemical Engineering seminar series, you are welcome to attend the following talk on process control technology, entitled: Development and Industrial Applications of Maintenance-Free High-Performance Virtual Sensing Technology
Abstract:
Virtual sensing technology has been widely used in various industrial processes to realize high product quality and productivity. In the chemical industry, for example, product quality is not usually measured in real time due to high investment and maintenance cost of on-line analyzers, thus soft-sensors have been widely used. However, their prediction accuracy deteriorates with time due to changes in processes characteristics and operating condition. In fact, the recent questionnaire survey confirms that model maintenance is the most critical issue concerning soft-sensors in the petroleum and chemical industries. The situation is quite similar in other industries such as semiconductor, steel, and pharmaceuticals. Since model maintenance or reconstruction is demanding for operators and engineers, practical, adaptive modeling techniques that can maintain high prediction accuracy need to be developed.
In order to realize maintenance-free high-performance virtual sensing, locally weighted partial least squares (LW-PLS) was proposed and has been successfully applied to various industrial processes. LW-PLS is a kind of Just-In-Time modeling method; thus it can construct a local PLS model adaptively on demand.
In this seminar, first, the recent questionnaire survey is introduced to get a general view of virtual sensing technology in the process industry. Then, the concept and algorithm of LW-PLS are described, and its potential is demonstrated through latest applications of LW-PLS in the petrochemical, steel, semiconductor, and pharmaceutical industries. Among them, the R&D in the pharmaceutical industry is emphasized because the paradigm of drug quality assurance system is shifting through quality by design (QbD) and process analytical technology (PAT). Finally, I would like to discuss the direction of research in this area.
