If that happens, Affirmative Defense should be considered. However, not knowing…

  • Cutting Control Valve Noise

    Jim Cahill
    3D printing is driving innovative low noise designs. Control valve noise is created by very high pressure drops across a valve, which generate high vapor velocities as a process fluid moves through the narrowed valve body passages. Low noise trim designs have been used to address this issue, but these are costly and reduce flow capacity significantly. A new solution uses parts made with 3D alloy printing, as we explain…

  • Meeting Regulatory Requirements with PRV Monitoring

    Jim Cahill
    At the 4C Health, Safety & Environmental Conference , Emerson’s Ricardo Garcia and Mo Fazl presented New Regulation Compliance Through PRV Monitoring Technologies.

  • Reduce Process Noise Without Pressure Drop

    Jim Cahill
    Oftentimes, compressible fluid flowing through piping creates high aerodynamic noise levels. These noise levels can induce safety concerns for plant staff, leading to equipment damage through vibration and process control issues. It’s critical to address this challenge to operate safely and reliably. One way to address this challenge is with the Fisher WhisperTube Modal Attenuator . This technology offers full-bore aerodynamic…

  • Isolation Valve Emission Reduction

    Jim Cahill
    Isolation valves are widely used throughout industrial plants and facilities worldwide. Though most perform well for their primary purpose of isolating one area of a process from another, many older models emit excess emissions. Regulations regarding these types of emissions are becoming much more stringent, as is pressure to improve upon corporate environmental, social, and governance (ESG) performance. In my March 2023…

  • Duke Energy Addresses Attemperator Issues

    Jim Cahill

In addition to the link to the presentation above, here is the link to the Control Valve Modeling and Control paper…

  • Improve Carbon Sequestration with Proper Valve Selection

    Jim Cahill
    Carbon capture and storage, often referred to as carbon sequestration, is attracting substantial investments worldwide due to environmental, social and governance initiatives. In the United States, the Department of Energy recently announced $3.7 billion of funding to sequester carbon dioxide in enhanced oil recovery (EOR) and other projects. But as our article in the March 2023 issue of Hydrocarbon Processing magazine…

  • Optimizing Valve Compressed Air Consumption

    Jim Cahill
    Energy efficiency is a significant focus area in many sustainability-related initiatives. Compressed air consumption is one important area to investigate. When considering technologies to reduce air consumption, looking beyond smart device air consumption data based on static analysis is essential. As an analogy, it would be like measuring fuel consumption while idling instead of when the engine is under load. I caught…
