  • Isolate and Protect in Hydrogen Dispensing Maintenance Operations

    Jim Cahill
    Double block and bleed valves enable maintenance on a section of process piping. They allow plant staff to block off and depressurize the section that requires maintenance. They consist of two block valves and one bleed valve. One of the valves blocks the upstream fluid from flowing. The bleed valve relieves the pressure from the downstream side to enable work to be performed. I share this as background for what is…

  • What are Bellows in Pressure Relief Valves?

    Jim Cahill
    We’ve had a couple of recent posts about pressure relief valves (PSVs), including Improving Pressure Relief Valve Safety, Reliability and Performance , and Accurately Monitoring Pressure Relief Events. In them was some discussion about conventional PSVs and ones with bellows. I wanted to learn more, so I found this great explainer video on YouTube. The video, What’s the Difference Between a Conventional and Bellows…

  • Identifying and Minimizing Fugitive Emissions from Control Valves

    Jim Cahill
    Control Valves would control ideally the process without any interface to the outside. Although, that’s not practical with today’s technology. Control valves are by design an interface between the process and the outside. This interface can cause some level of fugitive emissions, which are unintentional leaks from the process. Now whether the leak is below 3 ppm, which is essentially negligible, or over 500 ppm, which…

  • Mitigating Control Valve Noise

    Jim Cahill
    Manufacturing and production facilities tend to be noisy, especially where fluids flow through pipes. Control valves can be one of the sources of noise contributing to these conditions. In a Chemical Engineering article, Reducing the Noise from Control Valves , Emerson’s Mark Nord describes ways to reduce noise levels emitted from these control valves. He opens by describing decibels and the dBA scale in how it corrects…
