This techno-economic report focuses on cryogenic and non-cryogenic air separation technologies that separate air into commodity gases such as oxygen, nitrogen, and argon.  Five players dominate the global market, but many regional suppliers also compete on a local level, providing consumers with many supply choices.  The report profiles the major global licensors, describes cryogenic and non-cryogenic technologies to produce oxygen and nitrogen, provides process economics for different production routes, and summarizes commercial applications and market drivers for air separation gases.
