Rugged and Reliable Molecular Sieve Dryer Switching Valves
Jim Cahill
Natural gas and hydrocarbon liquids undergo many processing steps to final products. Dehydrating hydrocarbons is a key step before further processing, such as fractionation and liquefaction. Molecular sieve dryers, known for their efficiency and based on the adsorption principle , are the standard way to accomplish dehydration. Emerson’s Olivier Beyerman shared some background and considerations on this application. …

Control Valve Selection for PEM Electrolyzers
Jim Cahill
Renewable or `green’ hydrogen, produced by the electrolysis of water, using renewable electricity, has been described as the `fuel of the future’. However, companies such as Plug Power are building cost-effective green hydrogen ecosystems that are already rapidly advancing its role in decarbonizing industry and transport. Plug Power is the world’s largest user of liquid hydrogen, and has also developed its own proton…

Crucial Role for Valves, Regulators & Actuators in Blue Hydrogen Production Podcast
Jim Cahill
You may have heard of various color adjectives used to describe hydrogen production based on the amount of CO2 produced as a byproduct. Green hydrogen comes from renewable energy sources, powering an electrolyzer to split water into hydrogen and oxygen. Blue hydrogen is produced from typical sources like natural gas, but the CO2 produced as a byproduct is captured and stored away. This decarbonization process is one…

Valve Trim Innovations in Aerodynamic Noise Attenuation
Jim Cahill
Noise from flowing fluids can be a problem in many production processes. Control valves can sometimes be the source of some of the noise being generated. This pipeline noise is unfavorable to personnel safety, regulatory compliance, and plant reliability. With the demanding challenges from day-to-day operations, an unpredictable future, and nearing deadlines for sustainability goals, how do you address this challenge…

Moving Beyond Pneumatic Standalone Controllers
Jim Cahill
Scattered across oilfield sites, tank farms, and isolated process units, standalone pneumatic controllers have been used for decades to locally control level, pressure, flow, and temperature in remote locations. However, these traditional devices have limitations, and many vendors no longer offer or support them. My article in the April 2024 issue of InTech , titled “ When Pneumatic Standalone Controllers Age Out ,…

Control Valve Selection in Plastic Pyrolysis Applications
Jim Cahill
Since their introduction over a century ago, plastic products have become ubiquitous. Unfortunately, plastic waste degrades very slowly, and over time it breaks down into microplastics that harm the environment. Some efforts to address this problem involve replacing plastics with biodegradable alternatives, while others seek to recycle plastics after use. However, recycling plastic is difficult compared to materials…

Addressing Incorrectly Specified Valves
Jim Cahill
Discrepancies between actual operating conditions and initial design specifications often lead to equipment problems, requiring coordinated and prompt action from plant personnel and partners. K+S Potash Canada faced such challenges with their control valves in a new plant near Moose Jaw, Saskatchewan. Our article on pages 45-48 in the April 2024 issue of Global Mining Review , titled “ Under Control ,” describes how…

Digital Valve Controller Considerations
Jim Cahill
The electro-pneumatic positioner was introduced in the 1970s to correctly align and stabilize control valve position under variable instrument and process conditions. In subsequent decades, the electro-pneumatic positioner evolved into the more capable digital valve controller, but all the new features these devices provided often made configuration and troubleshooting more complicated. My cover story in the March 2024…

Improving Regulatory Compliance with Pressure Relief Device Monitoring
Jim Cahill
I caught up with Emerson’s Ricardo Garcia , who shared an update on the MON PRD regulations for miscellaneous organic chemical (MON) emissions from pressure relief devices (PRDs). The first U.S. National Emission Standards for Hazardous Air Pollutants (NESHAPs) were initially required by the 1970 Clean Air Act (CAA). These standards were developed for sources and source categories determined to pose adverse risks to…

Emerson’s Adam Attig & Ricardo Garcia presented Eliminating Unseen Threats: Innovation in Bellows Leak Detection for PRVs at the 2024 4C Health, Safety & Environmental Conference. They opened their presentation by defining the concept of back pressure. Back pressure is pressure present at the outlet of the pressure relief valve (PRV). There are two main categories of back pressure: built-up and superimposed. Back pressure…
