Title
Image-based Sensors for Control of Particulate Processes
Abstract: On-line monitoring of particle shape and size distribution is a challenge frequently faced by the traditional pharmaceuticals and fine chemicals industries. The control of particulate processes is particularly compounded by the lack of process understanding and in-situ sensors. With regulatory initiatives such as the US Food and Drug administration’s (FDA) Process Analytical Technology (PAT) program for the pharmaceutical industry and the ongoing improvement in real-time imaging hardware (exemplified by Focused Beam Reflectance Measurement FBRM and Particle Vision and Measurement PVM both from Lasentec) there is a growing interest to develop control technologies using advanced imaging sensors. In this work I will describe some of our research in image analysis targeted at real-time control of crystallization processes.About the Speaker: Rajagopalan Srinivasan is an Associate Professor in the Department of Chemical & Biomolecular Engineering at the National University of Singapore. He is concurrently a Principal Scientist at the Institute of Chemical & Engineering Sciences where he leads the Process Systems & Control team. Raj received his B.Tech from IIT Madras in 1993 and his PhD from Purdue University in 1998 both in Chemical Engineering. He worked as a research associate in Honeywell Technology Center Minneapolis before joining NUS. Raj’s research program is targeted towards developing artificial intelligence and systems engineering approaches for process design & control and enterprise optimization.
