Our solutions
Gas Purification
Transforming raw gases into ultra-pure commodities. We engineer high-grade purification solutions for the semiconductor industry and CO₂ liquefaction solutions for the energy transition.
Mastering absolute purity
Whether you are manufacturing the next generation of microchips or driving the circular economy, molecular precision is everything. Air Liquide designs and manufactures cutting-edge purification and liquefaction units. By leveraging cryogenic adsorption and advanced distillation, our systems guarantee unmatched purity, uncompromising safety, and optimized operational costs.
-
Stripping contaminants like O₂, CO, and CH₄ down to < 1 ppb for zero-defect chip manufacturing.
-
Transforming raw biogenic emissions into premium, safe, food-grade CO₂
-
Cryogenic separation techniques that eliminate consumable cartridges, lower energy use, and minimize downtime.
Frequently Asked Questions
Why choose ULTRAL cryogenic purification over Getter-type chemical purifiers?
Unlike Getter purifiers that rely on chemical consumption and require regular, costly cartridge replacements, our ULTRAL H2 system utilizes cryogenic adsorption. Its twin-column design automatically regenerates itself, resulting in zero consumable waste, significantly lower OPEX, and truly continuous 24/7 operation.
What specific impurities do your electronics-grade systems remove?
Our high-grade systems utilize chemisorption and cryo-trapping to eliminate critical impurities including nitrogen (N₂), oxygen (O₂), methane (CH₄), carbon dioxide (CO₂), water (H₂O), and carbon monoxide (CO) down to sub-ppb levels (< 1 ppb).
How does the CO₂ system support sustainability and the energy transition?
Biomass treatment generates a raw CO₂ gas stream. Instead of venting this gas into the atmosphere, our liquefaction units allow operators to capture, purify, and liquefy it. This creates a valuable, food-grade secondary revenue stream while preventing harmful emissions, directly supporting a circular economy.
What kind of engineering challenges do your teams tackle in purification?
Our engineering talents work at the bleeding edge of thermodynamics and fluid management. This includes developing fail-safe systems to safely manage highly toxic and flammable gases like High Grade CO , and designing autonomous, self-regenerating cryogenic beds that achieve the strict analytical purity required by the world's most advanced semiconductor fabs.
