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. […]

Donations of automation equipment to colleges and universities are an important way to build the skills of the next generation of automation professionals. I’ve share a few stories in the past (examples here and here). A colleague shared an example of how these donations extend globally. He pointed to a partnership between Emerson and the […]

I plucked this story from a growing and vibrant, “inside the Emerson firewall” community. This community connects Emerson global sales, project, and application folks together, primarily to ask about references–“has this has been integrated with that” sort of exchanges. The particular question was about examples of distillation control. Emerson’s Doug White responded with an example […]

Neural networks, not the ones in our brains, but the ones that came out of the artificial intelligence research, began back in the 1940s. This advanced process control (APC) technology has been used in the process industries for many years for applications ranging from virtual sensors to end of batch prediction. Neural networks have been […]

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 […]
