Collaboration between Universities and Automation Suppliers
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...
Improved, Efficient Crude Fractionation Unit Operation
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...
Neural Network for Product Quality Estimation
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...
Measuring pH and Conductivity Wirelessly
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...
Improved Distillation Column Recovery and Reduced Energy Usage
Here's another great presentation from the recent Emerson Exchange from refining & chemicals industry solutions director, Pete Sharpe. You may recall Pete from earlier process optimization-related posts. His presentation, SmartProcess Distillation Application...
Statistically Uncovering Problems to Lower Heat Rate
I saw news of a combustion optimization and simulation project award for a 385 megawatt power station in the U.S. It reminded me of Emerson's Jeff Williams presentation on the topic of emissions reduction equipment optimization at the last Emerson Exchange. He also...
