As oil prices have remained lower for many months, many oil & gas producers have shifted their priorities from new production to optimizing existing production and reducing operating costs with the assets currently in place. In the quick, 2-minute video,...
Let's highlight a few more of the accepted presentations from Emerson experts presenting at the October 12-16 Emerson Exchange conference in Denver. You can download a spreadsheet with the entire list of accepted abstracts here. These presentations share experiences,...
Process measurement devices are installed where required to monitor, control, and safely shutdown the process. But often, additional measurements combined with the existing ones can help to improve several areas of process operations performance. I saw a chart from...
You've likely heard the phrases pervasive sensing and the industrial internet of things (IIoT) tossed about. But what are some real examples of how they help process manufacturers and producers? I came across this excellent case study on the use of wireless...
Author: Lou Heavner Part 1 in the series addressed basic distillation column control and Part 2 explored inferential composition measurement and control design. In today's post I share how we need to consider how to close the material balance and the application of...
The PID controller entry in Wikipedia highlights the beginning of proportional+integral+derivative control going all the way back to the 19th century: PID controllers date to 1890s governor design.[2][3] PID controllers were subsequently developed in automatic ship...
The constant improvements in electronics and communications technology has made many things much easier to track, monitor and control. In a hazardex article, The advantages of pervasive sensing, Emerson's Deanna Johnson describes how sensing technologies, once...
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...
Lou Heavner explains how control has been traditionally performed on distillation columns.
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 year, some controversy broke out in the process automation and control community about the use of Lambda tuning for proportional-integral-derivative (PID)-based control. In a post, Lambda Tuning-Yeah or Neah?, we offered a differing view to a Control magazine...
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...
