Ceramic membrane development for oxygen supply to gasification applications and Syngas generation.

Author(s) : ALLAM R. J., ARMSTRONG P. A., STEIN V. E., et al.

Summary

In partnership with the US Department of Energy, an Air Products-led team is developing a new air separation technology - Ion Transport Membrane Oxygen (ITM Oxygen) - based on ceramic membranes that selectively transport oxygen ions when operated at high temperature. 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 energy-rich, vitiated, 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 combustion or gasification, making IGCC an ideal application for ITM Oxygen co-production technology. The economic benefits to IGCC projects that use ITM Oxygen are projected to be significant: the cost of the oxygen plant is lower by over one-third (more than 33%) compared with conventional cryogenic distillation.
