A New Air Separation Technology, Ion Transport Membrane
A new air separation technology—Ion Transport Membrane Oxygen (ITM) is an enabler for advanced clean power and can reduce the cost of gasification. ITM is based on ceramic membranes that selectively transport oxygen ions when operated at high temperature and is being developed by an Air Products-led team in partnership with the U.S. Department of Energy (DOE). Under the influence of an oxygen partial pressure driving force, the ITM oxygen process achieves a high-purity, high flux separation of oxygen from air. By integrating the oxygen-depleted, non-permeate stream with a gas turbine system, the overall process co-produces high-purity oxygen, power, and steam if desired. As a result, the technology is ideally suited for advanced power generation processes that require oxygen as a feedstock for gasification or combustion, making IGCC and oxygen-enriched combustion ideal applications for ITM Oxygen technology.
