Air separation plants generally produce oxygen, nitrogen, argon and – in some special cases – other rare gases (krypton, xenon, helium, neon) by cryogenic rectification of air.
The products can be produced in gaseous form for pipeline supply or as cryogenic liquid for storage and distribution by truck.
Tonnage air separation plants are plants that are individually designed for the specific demands of our customers. Daily oxygen production capacities are between 450 t/d and 30,000 t/d. Within the last 20 years Linde has built approximately 100 tonnage air separation plants.
