  • Alternative Air Separation Technologies

    Cryogenic Air Separation (ASU) the principles invented one century ago (Dr. Carl von Linde) developed for large volumes of oxygen and nitrogen with high purities developed for large volumes of oxygen and nitrogen with high purities commercialized for industrial application in a wide range the source for Industrial Gas Companies supply schemes Continuous development and improvement , >25% power saving possible

    Polymeric Membranes and Moleculare Sieves (PSA, VSA) advantageous for small volumes - at lower purities produced at ambient temperatures and as needed on-site

    Oxygen Production by Chemical Air Separation (MOLTOX) Developed and pilot tested by Air Products with DOE funding in early 1990s >40% power saving predicted, compared with cryogenic processes Status and future of the process unknown (material- and corrossion problems)

    High Temperature Ceramic Membranes (ITM) Developed and pilot testing (5t/d) since 2005 by Air Products with DOE funding
