Systems to combat air pollution from combustion processes generally inject a chemical into the gas stream that is designed to neutralize a specific pollutant. For example, limestone slurry is sprayed into sulfur-dioxide-laden flue gas to neutralize the potential acid...
The urea process poses extreme challenges for control valves, including high pressures and pressure drops, elevated temperatures, and corrosive carbamate solutions. Our article in the June 2025 issue of Hydrocarbon Processing, titled “New alternatives for severe...
Over the last century and more, a few industries have developed large-scale integrated production and distribution systems, covering the span from source to final consumer. Oil and gas are the most obvious, covering all aspects of industrial, commercial, and consumer...
Emerson’s Andrew Cureton presented Don’t Overthink It–Wireless for Chemical Industry MON Mandate Compliance at the 2025 Emerson Exchange Conference. His session explored the monitoring requirements of the U.S. Environmental Protection Agency rules for pressure relief valves.
In a world where field operations depend on fast, reliable, and secure data transmission, sticking with outdated wireless field gateways can silently sabotage your performance. Legacy devices will still in operation, but they're often the weak point — exposing systems...
Control valves are critical in the applications within the ammonia production process. Some applications are severe services that could cause challenges to the valve operation, impacting the process efficiency and may disrupt the production or even damage the equipment.
I work with a lot of engineers and other mechanically minded people, but I don’t know many that work on their own cars. Maybe an oil change here or there, but the sophistication of today’s engines and internal networks makes DIY work so impractical that it really must...
Most of today’s electric vehicles (EVs) rely on lithium-ion (Li-ion) batteries due to their high-energy density. As these batteries have become increasingly more advanced, so has the manufacturing process required to produce them—a complex interplay of chemical...
Ammonia production, a cornerstone of global food security, carries a significant environmental footprint. While its output is essential for producing fertilizers to feed billions, it accounts for 1.8% of global CO2 emissions, releasing around 500 million tonnes...
Only about 9% of the world’s plastic waste is recycled, according to the Organisation for Economic Co-operation and Development (OECD). Many post-consumer plastics are considered unrecyclable via traditional mechanical methods and end up in landfills, get incinerated,...
If a trip to the doctor for a routine checkup resulted in a call for a drastic and costly medical procedure, there would be a legitimate reason to request a second opinion. If we apply the same concept to a major process unit in a refinery or chemical plant, an alarm...
At the Valve World 2024 Conference, Emerson’s Knut Riegel presented Selecting Valves for Chemical Process Applications. His presentation addressed the chemical industry’s role in Germany, key principles to meet the needs of this industry, and the engineered valve solutions to address these needs.
