Webinar Recording: How to Get the Most out of Control Valves

The data that is really needed when selecting and sizing a control valve is rarely understood and specified, which leads to excessive variability originating from the valve. In this presentation, ISA mentor Greg McMillan discusses pervasive problems and rampant misconceptions. He then provides guidance—supported by test results—on how to select a good throttling control valve. […]

Webinar Recording: Model-Predictive Controllers for Cost Optimization

Having two small model-predictive controllers (MPCs) available as a standard option in a distributed control system (DCS) shows much better performance than the previous PID for product pH and assay control, reducing off-spec product and raw material use. The MPC effectively deals with a recycle stream and a level override scheme that can change production […]

Webinar Recording: Beginner’s Guide to Vacuum Ramping

Understanding the fundamental principles and the limitations of process equipment and instrumentation is seen to be essential to developing the proper control system for separation of multiple batch components by vacuum stripping. Danaca Jordan, ISA Mentor Program protégée, presents the results of alternate strategies along with their limitations. A proposed solution is given at the […]
