Improvements are still needed to gas separation processes to gain industry acceptance of coal gasification systems. The Ion Transport Membrane (ITM) technology, being developed by the US Department of Energy and its partners, offers an opportunity to lower overall plant cost and improve efficiency compared to cryogenic distillation and pressure swing adsorption methods. The technology is based on a novel class of perovskite ceramic oxides which can selectively separate oxygen ions from a stream of air at high temperature and pressure. Those ions are transported across the ITM leaving non-permeate air which can be integrated with a fuel-fired gas system, enabling co-production of power and steam along with the concentrated, high-purity oxygen. The project is at the second phase, to scale up the ITM Oxygen ceramic devices to demonstrate the technology at the 1-5 tpd capability in the Subscale Engineering Prototype. A third phase to demonstrate commercial viability extends to the end of the decade. 2 figs.
