Effect of Mechanical Design – UA

The product of the overall heat transfer coefficient and area (UA) determines the controllability of temperature processes. The deterioration of the UA is a particular concern for crystallization and polymerization processes. Frosting and fouling can decrease process efficiency and production rate even if the controllers are retuned. For exothermic reactors, a decrease in the UA …

PID Unleashed

The full power of the PID is rarely utilized. The section Industrial-Applications-of-PID-Control in the soon to be book published by Springer titled PID Control in the third Millennium: Lessons Learned and New Approaches explores key PID features and provides examples for addressing challenging applications and control objectives for common unit operation applications in the process industry.
