Specialized Control Valves for Semiconductor Ultrapure Water Applications
Jim Cahill
Effective production of minuscule silicon chips requires water with close to zero impurities. This ultrapure water must be produced in a system made up of special components, including control valves with very specific features. The latter issue is the subject of my article in the July 2023 issue of Processing, titled “ Control Valve Selection for Semiconductor Ultrapure Water Applications ,” please find a summary below…

An Alternative to Balanced Bellows in Pressure Relief Valves
Jim Cahill
Pressure relief valves (PRVs) protect pipes, manifolds, and vessels by relieving overpressure conditions. For applications that do not vent directly to atmosphere, PRV designs with metal bellows can eliminate the effects of backpressure, but these devices are prone to failures. Below is a summary of my article in the July 2023 issue of Processing, titled “ Addressing bellows failures in relief valve applications ,”…

Three Steps to Maximize Your Next Outage with a Data-Driven Valve Maintenance Strategy
Jim Cahill
Are you asking yourself why we prioritize the same valve list over and over again for every outage? When you started as a reliability or maintenance engineer, your manager handed you a list of valves to service during each outage. You’ve been using that list repeatedly at this point and you may occasionally discover that certain valves don’t require maintenance during the outage. If you are creating your own valve list…

Improve LNG Operations with Optimized Joule-Thomson Control Valves
Jim Cahill
Control valves in liquified natural gas applications must operate reliably under high pressure and cryogenic temperatures to achieve gas separation and liquefaction. This is especially true for the main cryogenic heat exchanger (MCHE), where the closely-coupled Joule-Thomson (J-T) control valves feeding the MCHE help optimize the operation of the most critical area in the entire process. My article in the Apr 2023 issue…

The Top 4 Key Performance Indicators (KPIs) to Improve Your Next Outage
Jim Cahill
You just completed your outage. You are ordering pizza for the team and starting to get back to a normal shift schedule. As you’re getting back to business-as-usual, you are finishing up open items and making sure there are no issues with any of the units that were brought down for maintenance. Now, it’s been a few weeks, a month after the units are all up and running and it’s time for the post-outage review. Capturing…

Emerson’s Marcio Donnangelo and Marcelo Dultra presented Reducing Data Complexity on Affirmative Defense Claims with PRV Monitoring System at the 2023 4C Health, Safety & Environmental Conference. Here is their presentation abstract: Despite the efforts to stay compliance, operation isn’t totally free from unauthorized events to happen. 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…

At the 4C Health, Safety & Environmental Conference , Emerson’s Ricardo Garcia and Mo Fazl presented New Regulation Compliance Through PRV Monitoring Technologies. Ricardo described how pressure relief valves are the last line of defense for over- and under-pressure conditions. They are self-operated mechanical devices that are typically off-grid/not connected, are pervasive across most plants that, can cause emissions…

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…
