Process Simulation – Part 5

The standard tools available in most process control systems may be used to create a dynamic process simulation. Such a simulation may be combined with the control modules to create an effective operator training system or to facilitate control system checkout. The techniques that may be used to create a dynamic process simulation and to …

Process Simulation – Part 4

In my March 14, 21, and 28th postings I summarized some of the basics associated with design and implementation of process simulation that are addressed in the book Control Loop Foundation – Batch and Continuous Processes. Simulations based on duplicating the process step response may be effectively used for operator training and control system check. …

Process Simulation – Part 3

This is the third posting on highlights of Chapter 15, Process Simulation, in Control Loop Foundation – Batch and Continous Processes. In my March 14 and 21st postings on process simulation I addressed some of the some basics associated with the integration of process simulation into a control system. In this posting we will start …

Process Simulation – Part 2

In my March 14 posting on process simulation I addressed some of the some basic technique that may be used to integrate process simulation into a control system. The P&ID often serves as the starting point in the development of a process simulation for control system checkout or operator training. In most cases, one process …

Process Simulation – Part 1

Process simulation can be an extremely useful tool when working with a control system. Thus, chapter 15 of Control Loop Foundation – Batch and Continuous Processes addresses how to add process simulations to a control system using tools that exist in most control systems. The material in this chapter on process simulation is broken into …

Commissioning Highly Interactive Process

At Emerson Exchange, 2011, I had the pleasure of working with Eric Chen, Research Associate, Pickle Research Center, University of Texas at Austin SRP and Willy Wojsznis, Senior Technologist, Emerson Process Management, to host a workshop that addresses commissioning of a skid process that is characterized by a high degree of process interaction. The size …

Recovery from a Process Saturation Condition

At Emerson Exchange, 2011, I had the pleasure of working with Daniel Coyne, Manager, Automation, BP America Inc., to host a workshop on Recovery from a Process Saturation Condition. The workshop addresses the improved recovery from a process saturation condition that is provided by the PIDPlus option of the PID function block in the DeltaV …

Wireless Online Process Metrics

It is hard to imagine that in this day and age we are relying on “after the fact” process performance analysis on a gross scale. I wonder if we still use spreadsheets and costs sheets to judge a process unit and operator performance. We can see differences in setpoints at a shift change but have …

Exceptional Opportunities in Process Control – Virtual Plants

Simulation was such an integral part of my job it is difficult for me to visualize a process control career without models. I was asked to join Engineering Technology (ET) at Monsanto in 1976 because I had developed a dynamic compressor model as the lead Instrument and Electrical engineer for what was the largest Acrylonitrile …
