Recovery Act: Development of Ion-Transport Membrane Oxygen Technology for Integration in IGCC and Other Advanced Power Generation Systems


Performer: Air Products and Chemicals, Inc.

Project No: FC26-98FT40343


Project Description

Air Products and Chemicals, Inc., (APCI) is currently developing ion-transport membrane (ITM) oxygen separation technology for large-scale oxygen production and for integration with advanced power production facilities, including gasification facilities. The ITM-based oxygen production process uses dense, mixed ion- and electron-conducting (MIEC) materials that can operate at temperatures as high as 900 degrees Celsius (°C). The driving forces for the membrane oxygen separation are determined by the oxygen partial-pressure gradient across the membrane. The energy of the hot, pressurized, non-permeate stream is typically recovered by a gas turbine power generation system. The development of the ITM process will support reduced capital cost and parasitic load of air separation systems compared to that of currently available cryogenic air separation technology. Because air separation is a critical component of the gasification process for power production, any reduction in the cost of this process component will in turn reduce the overall cost of gasification, thereby making the process more competitive.
