Cecil L. Smith, PhD, has over thirty-five years' experience in process control, his expertise encompassing every control technology being applied in industrial production facilities. In continuous processes, he has worked with oil refining, pulp/paper, power generation, and ore processing. In batch processes, he has experience with both single-product processes (such as PVC reactors and pulp digesters) and the multiproduct (flexible batch) processes that are the norm in specialty chemicals. His primary focus is on designing a control strategy for a process and then commissioning the controls; that is, the process aspects as opposed to systems aspects. He also develops and teaches continuing education courses for practicing engineers on various aspects of process control and instrumentation.
