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. APCI has a co-current ITM project, FE0012065.

Project Benefits

This Air Products and Chemicals, Inc. project focuses on increasing the efficiency and reducing the capital cost of oxygen (O2) production through development and demonstration of ion transport membrane (ITM) technology. ITM uses mixed ion and electron conducting materials to produce high temperature/high purity O2 at significantly lower capital than state-of-the-art cryogenic O2 production systems. Specifically, this project will demonstrate a pilot-scale ITM O2 production system, and construct a facility capable of producing the complex modules at a commercially relevant rate.
