World-Class Solutions

Air separation plants (ASUs) are used to separate atmospheric air into its primary components, including nitrogen, oxygen, and argon, along with smaller amounts of other gases.

ASUs commonly utilize fractional distillation - also called cryogenic distillation - to deliver industrial gases including nitrogen, oxygen and often co-produce argon, CO2 and hydrogen.

Non-cryogenic air separation plants include membrane, pressure swing adsorption (PSA) and vacuum pressure swing adsorption (VPSA).

MIG delivers best-in-class solutions for all air separation plant types, including both cryogenic and non-cryogenic ASUs and can help you determine the optimal solution for your operations. Contact us today to learn more.
