Author: Lou Heavner In part 1, we looked at how control has been traditionally performed on distillation columns. We’ll look at some improvements in today’s post. Inferential Composition Measurement One thing required for distillation column control is product quality measurement. This is typically done with analyzers, but many columns are not equipped with online analyzers. […]
Author: Lou Heavner In this 3-part series on distillation column control basics, we’ll look at traditional control and modern approaches to improve control robustness. For background, you can find a good write up on industrial distillation in Wikipedia. In the distillation process, a feed mixture is separated by volatility or boiling point into 2 or […]
Just about all plants have a few “blind spots” where instrumentation has not been installed due to cost, installation difficulty, or other hurdle. ModelingAndControl.com’s Greg McMillan is giving an AIChE virtual local section presentation, Wireless Measurement and Control-Opportunities for Diagnostics, Process Metrics, Inferential Measurements, and Eliminating Oscillations on August 25th at 10am EDT/ 14:00 UTC. […]
Update and bump: Greg’s article is now live on the ISA.org InTech website. Below is the original Dec. 15, 2009 post. I received an advanced copy of an article ModelingAndControl.com‘s Greg McMillan has recently completed, Exceptional Opportunities for Smart Wireless pH and Conductivity Measurements. In the article, he summarizes these opportunities: …for inferential measurements, solution […]
For those attending the Emerson Exchange with distillation processes, you don’t want to miss Emerson’s Lou Heavner‘s presentation, Advanced Distillation – 102. Lou is an advanced control consultant, whom you may recall from earlier posts. He’ll be presenting Wed, 9/30 at 4:15pm in the Sun 4 room and again Thurs, 10/1 at 9:00am in the […]
