Avoiding plant tests with dynamic simulation
A model-predictive controller based on models derived from first-principles dynamic simulation as an alternative to empirical models identified from plant test data is presented
Optimize steam system control with dynamic simulation
Dynamic simulation was used to evaluate two control schemes of a steam utility system
HP Control: Condenser hot vapor bypass control
What is the worst mistake? It is the one that is repeated in practically every refinery, and yet, we haven't managed to learn from it. I have chosen to discuss the very simple distillation column pres..
HP Control: Part 2—What happened to simple useful APC techniques?
This is the second part of my interview with Greg Martin about simple control techniques, unjustifiably retired. In this part we address single-input, single-output (SISO) predictors and simple engine..
Online transfer from an analog electronic control system to a modern DCS
Proper planning, personnel training and interdepartmental communications were keys to the success of this project
Fieldbus in your future: Training overcomes complexity issues
A comprehensive instruction program can help plant management prepare personnel for the new era of digital process control
Satisfying safety standard competency requirements
Deploying a robust, IEC conformant safety instrumented system requires uncompromised competency in every step of the process
