Industrial Gas Applications of Cryogenics

by Pierre Meurgey | Sep 2, 2026 | Cryogenic consulting

Same Molecules, Different Constraints Cryogenic systems support large-scale production, storage, and delivery of industrial gases such as oxygen, nitrogen, argon, and CO₂. However, each application creates very different requirements for flow rate, pressure stability,...

CO₂ Cryogenics and Phase Behavior

by Pierre Meurgey | Aug 26, 2026 | Cryogenic consulting

Operating on a Narrow Thermodynamic Edge CO₂ cryogenic systems behave very differently from LNG or nitrogen systems. The CO₂ phase diagram creates a much narrower operating window. Solid formation risks can appear within normal operating ranges, which makes system...

Defrosting and Operational Cycles of Vaporizers

by Pierre Meurgey | Aug 19, 2026 | Cryogenic consulting

Managing Performance Over Time Ambient air vaporizers are simple, reliable, and widely used in cryogenic applications. However, their performance changes over time during operation. Frost formation gradually reduces heat transfer efficiency, making operational cycling...

Cryogenic Valves and Instrumentation

by Pierre Meurgey | Aug 12, 2026 | Cryogenic consulting

Sealing the Cold Cryogenic valves and instrumentation operate under extreme conditions. These components must withstand very low temperatures, large thermal gradients, and frequent phase changes. Equipment that performs well at ambient conditions often fails at −160...

Energy Efficiency in Cryogenic Systems

by Pierre Meurgey | Aug 5, 2026 | Cryogenic consulting

Where the Energy Really Goes Cryogenic processes are inherently energy-intensive. This applies to liquefaction, storage, and regasification. Efficiency is not only about equipment performance. It also depends on minimizing irreversible losses across the entire system....

Small-Scale vs Large-Scale Liquefaction Technologies

by Pierre Meurgey | Jul 29, 2026 | Cryogenic consulting

Efficiency vs Simplicity Liquefaction technologies are not one-size-fits-all. The optimal solution depends strongly on plant capacity, operating profile, and available infrastructure. At the core, the trade-off is clear: thermodynamic efficiency versus system...
