  • Tips for New Process Automation Folks: Variability Appearance and Disappearance

    Gregory K McMillan
    The post, Variability Appearance and Disappearance originally appeared on the ControlGlobal.com Control Talk blog. Particularly confusing is variability that seems to come out of nowhere and then disappear. There are not presently good tools to track down the sources because it turns out most of them are self-inflicted involving automation system deficiencies, dynamics and transfer of variability. You need to understand…

  • Emerson Automation Experts: Helping Hands for Your Valves

    Jim Cahill
    Imagine you have been tweaking and tuning one of your control loops and have the perfect PID [proportional-integral-derivative] settings. Everything is working great for several months until it isn’t. Chances are that it’s the part of that loop doing all the manual work to keep the process running smoothly—the control valve. A poorly performing control loop can cause increased variability, increased probabilities for…

  • Emerson Automation Experts: Modernization of DCS and PLC with Electronic Marshalling

    Jim Cahill
    Scott Ross Now, with many control systems being 30+ years old, most of these legacy systems have been placed in to end of life or retired lifecycle status. This means no further factory support is available. I caught up with Emerson’s Scott Ross about some of the choices that must be considered moving forward. Manufacturers and producers face options whether to modernize to a newer family of distributed control systems…

  • Tips for New Process Automation Folks: Lowdown on Turndown

    Gregory K McMillan
    The post, Lowdown on Turndown , appeared first on the ControlGlobal.com Control Talk blog . There are a lot of misconceptions on what is the turndown capability of measurements and final control elements (e.g., control valves and variable frequency drives). Here is a very frank concise discussion of what really determines turndown and things to watch for in terms of limiting factors. For flow measurements and final…

  • Emerson Automation Experts: Ethylene Furnace Automation, Control & Optimization

    Jim Cahill
    Pete Sharpe Author: Pete Sharpe Cracking furnaces are one of the most crucial parts of an ethylene complex. They set the production and yield for the entire plant. For furnace-limited plants, when a furnace is down, whether for maintenance or decoking, production is lost. Poor control and sub-optimal furnace operations lead to lower yields, more frequent decoke cycles, increased energy costs, and higher health,…
