  • Improving Pressure Relief Valve Safety, Reliability and Performance

    Jim Cahill
    I saw the new Crosby Balanced Diaphragm and Bellows Leak Detection pressure relief valve (PRV) solution at this past Emerson Exchange conference. The innovations in it were pretty impressive. The news came out today, Emerson Reinvents Pressure Relief Valves to Improve Performance and Reduce Emissions , which shares how this solution improves “…performance, safety, and reliability while reducing emissions”. The Balanced…

  • Accurately Monitoring Pressure Relief Events

    Jim Cahill
    Pressure relief valves are essential in keeping process manufacturing and production operations safe and operating reliably. But, as environmental regulations grow stricter, knowing how much fluid was vented is vital for regulatory reporting. In this under three-minute YouTube video, Anderson Greenwood & Rosemount Pilot Operated PRV Monitoring Delivers Unparalleled Accuracy , Emerson’s Ricardo Garcia shares how monitoring…

  • 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…

  • Wellhead Electrification Drives Optimization Program

    Jim Cahill
    At the 2022 Emerson Exchange conference, Prabhat Behera from Occidental (Oxy) shared insights and lessons learned from a wellhead electrification project. Puffer-Sweiven’s Jack Lee and Emerson’s Damian Trujillo joined him to provide additional context on the integrated model that brought together the application, product and services. Here is their session abstract: Shutdown valves installed at the wellhead for oil…

  • The Chip Shortage Continues: How Semiconductor Manufacturers Are Responding

    Jim Cahill
    The global chip shortage continues to put pressure on semiconductor manufacturers, who are searching for ways to increase production yields. One solution is to modernize operations with cutting-edge automation and data analysis tools. However, this is costly. Another option is to digitize components and work toward complete digitalization of the entire process. This would allow manufacturers to monitor and control operations…

  • Reduce Waste & Increase Efficiency in Clean-in-Place Processes

    Jim Cahill
    While the idea of adding costs to a food and beverage or pharmaceutical industry process like Clean-in-Place/Steam-in-Place (CIP/SIP) has not traditionally been an easy decision, in today’s industrial environment that has changed. With the retirement of experts, the lack of availability of workers, the increase in materials costs and narrowness of margins, the principal way for food and beverage and pharma companies to…

  • Avoiding Actuator Damage from Failed Components

    Jim Cahill
    Manufacturers and producers must think through their process safety on ways to mitigate risks against failure conditions in the components within a basic process control system (BPCS) or safety instrumented system (SIS). For instance, failures can occur on air filter regulators (AFRs) on valve actuators. I mention this because I connected with Emerson’s Riyaz Ali , who had a discussion with a major international oil company…

  • Partial Stroke Tests and Diagnostics for Emergency Shutdown Valves

    Jim Cahill
    Emergency shutdown valves perform the work of bringing the process to a safe state in the event of a hazardous condition. They must be periodically tested, because, unlike other valves, they may sit dormant for a long time. This 2:22 YouTube video, Emerson TopWorx DX PST with HART 7 , explains how this partial stroke and emergency shutdown valve controller controls and monitors these shutdown valves. To test the capability…
