In the late 1980’s Air Products identified a class of perovskite ceramic materials with high flux and separation selectivity for oxygenions. These materials have become the basis for a novel class of air separation technologies, referred to as Ion Transport Membranes(ITMs). Along with partners and through collaboration with the U.S. Department of Energy, Air Products has made substantialprogress in developing ITM Oxygen technology to be a cost effective method of oxygen production. ITM Oxygen integrates wellwith advanced power generation processes, as well as traditional energy intensive industrial processes requiring oxygen.The team has successfully demonstrated expected performance of commercial-scale modules in a prototype facility that produces upto 5 tons-per-day (TPD) of oxygen. Continued operation of this unit has verified thermal and pressure cycle performance, and tested anumber of component designs and operating scenarios for next phase scale-up. Next phase pilot unit is in construction, and majoroperation is planned in 2013. This Intermediate Scale Test Unit (ISTU) is designed to produce up to 100 TPD of oxygen integratedwith turbo-machinery and co-production of power. Data from the 100 TPD unit will provide the design basis for a much larger plantthat could produce 2000 TPD. In parallel, work has also begun to expand ceramic fabrication capacity to support these developments.This paper will present an overview and update of the ITM Oxygen development effort, including testing of commercial-scale ceramicmodules and operating scenarios, next-phase scale-up designs, ceramic manufacturing expansion work, and developing commercialprocess integrations and economic analyses toward gasification, gas turbine, oxy-combustion, and other energy-intensive industrialapplications. A commercialization timeline will be discussed.
