Document Summary
Process design: combine reactors and separators in the most economical way. Process is never at steady state in a plant, always fluctuations. Or may have to shift operating states b/c prices change. But still need to enforce production requirements to keep it efficient and profitable. Safety too, need to control pressures and temperatures. Process control: stems from the need to monitor the transient process operation and adjust process conditions (flow rates) Want to do it in an automated way to enforce production requirements and meet safety and environmental constraints. This class: analyze transient (dynamic, unsteady state) process behavior, design controllers (automated mechanisms) to achieve process objectives. Here, we use theory and engineering aspects: notion of feedback. This = center of process control, prevalent in all physical, biological, and social systems. Focus on lecture notes to get best understanding. 1st hw assigned friday and due on wednesday. No final, but all midterms are cumulative of whatever has been taught before that.
