Cryogenic Distillation Columns: Precision Separation at Low Temperatures

by Pierre Meurgey | Sep 30, 2026 | Cryogenic consulting

Cryogenic distillation forms the heart of every Air Separation Unit (ASU). It separates air into high-purity oxygen, nitrogen, and argon by taking advantage of their different boiling points at cryogenic temperatures. Because these boiling points differ by only a few...

Plate-Fin Heat Exchangers (PFHE): Compact Efficiency for Cryogenic Applications

by Pierre Meurgey | Sep 23, 2026 | Cryogenic consulting

Plate-fin heat exchangers (PFHEs) are at the heart of most cryogenic processes, including LNG plants, air separation units (ASUs), and hydrogen liquefaction systems. Their compact design, high heat transfer efficiency, and ability to handle multiple process streams...

Cryogenic Compressors: Design and Selection for Cryogenic Applications

by Pierre Meurgey | Sep 16, 2026 | Cryogenic consulting

Cryogenic compressors play a central role in LNG plants, air separation units, hydrogen systems, and industrial refrigeration. They do much more than increase gas pressure. The right compressor improves energy efficiency, reduces specific energy consumption (SEC), and...

Digitalization in Cryogenic Plants

by Pierre Meurgey | Sep 9, 2026 | Cryogenic consulting

From Reactive to Predictive Operation Cryogenic systems are inherently dynamic. Thermal transients, phase changes, and changing demand continuously affect performance. These operating conditions make system management more complex than in many conventional industrial...

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...
