Author: Sonal Gilani In an earlier post, Improving Energy Efficiency in Thermal Oxidizers, I highlighted how switching control loops from manual to automatic mode improved overall efficiency. Emerson's James Beall shared a second story on this thermal oxidizer...
Author: Sonal Gilani Thermal oxidizers are used to destroy the waste gases containing volatile organic compounds (VOC) and volatile hazardous air pollutants (HAP) by raising the temperature of the material above its auto ignition point in the presence of oxygen. The...
Knowledge sharing need not be limited to one week conferences like the recent Emerson Exchange conference. I mention this to highlight an excellent discussion thread in Emerson Experts Forum in the Emerson Exchange 365 community. The thread, MPC [Model Predictive...
For manufacturers with energy intensive processes, such as the petrochemical industry, the shale oil and gas boom in North America has led to lower feedstock costs. In this short, 1:34 video, Emerson's James Beall describes some of the challenges faced by plants to...
Having trouble with an oscillating integrating process? Have too much variability in a self-regulated process? Need a refresher about the essentials of Lambda (λ) tuning? Then check out James Beall's workshop at the Jan. 21–23 Texas A&M University 2014...
Last week, Emerson Consultant James Beall was working with a major U.S. plastics facility on the Texas Gulf Coast, helping the firm figure out how it might save some of the money it spends on distillation energy by using Emerson's Smart Process Distillation Column...
Emerson's Chris Womack discusses process control with IEC 62591 wireless devices in today's guest post. Using wireless devices in process control still isn't that common, but it's going to be. With its quick and easy installation, wireless technology is often used for...
I received an interesting story from Emerson's James Beall about a process manufacturer with a process filled with many fermentors. They were being converted over from Provox control systems to DeltaV systems. pH control was a key part of the plant's fermentation...
Earlier this week, I highlighted a presentation by Emerson's James Beall, Fundamentals of Modern Loop Tuning. I shared his approach for tuning self-regulating loops and the sequence to tune interacting loops. Today, I'll share some guidance from the portion of the...
I've highlighted a few Emerson presentations for this week's ChemInnovations conference in New Orleans. Emerson's James Beall, a 30-year veteran in process control and chairman of the ISA 75.25 committee on control valve performance testing, shared his ChemInnovations...
Emerson's James Beall presented Master the Mystery and Marvels of DeltaV MPC at the 2012 Emerson Exchange. His abstract: Have you found the perfect application for Model Predictive Control (MPC) but don't know how to get started? Or perhaps you have implemented an MPC...
A quick look at the headlines shows energy prices continuing their high levels. For most process manufacturers, energy is one of the highest operating expenses. I was in meetings last week with several of the industry consultants highlighted on this blog including...
