Project No: FC26-98FT40343


Project Scope and Technology Readiness Level


This project will develop and scale up a novel, non-cryogenic air separation technology with lower capital cost and energy requirements than conventional cryogenic processes to produce high-temperature/high purity oxygen synergistically with integrated gasification combined cycle (IGCC) and other advanced power generation technologies.

This project has been through several phases, with some objectives from previous phases already completed. The initial activities focused on materials and process R&D and the design, construction, and operation of an approximately 0.1 ton per day (TPD) Technology Development Unit (TDU). Subsequent activities were focused on testing the performance of full-size ITM Oxygen modules in a 5 TPD sub-scale engineering prototype (SEP) facility specially designed for this purpose. Tests conducted in the SEP generated process information for the current activity.

The current scope includes increasing the scale of the engineering test facility from 5 TPD to approximately 100 TPD of oxygen in an intermediate-scale test unit (ISTU). The ISTU features oxygen production from an ITM-containing vessel coupled with turbo-machinery for power co-production, and will provide data for further scale-up and development. In addition, and to support a larger test facility, expanded efforts in the areas of materials development, engineering development, ceramic processing development, and component testing are being undertaken. The project will also assess the overall reliability of the process relative to the industry standard.

Current scope also includes the development of a dedicated large-scale ITM manufacturing capability (CerFab), funded under the American Recovery and Reinvestment Act of 2009 (ARRA), needed to support a future 2000 TPD oxygen test facility. APCI will design, construct, and commission the CerFab and assess its operating capabilities during a short-term module production campaign. Advanced materials and production techniques will be developed to support the design and operation of the CerFab. The manufacturing capability will be based on ongoing development work in ceramic material and membrane module processing with an emphasis on industrial carbon capture, as well as knowledge developed during the earlier part of the program. In addition, assessments of low-carbon industrial applications of ITM technology will be made.

The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE’s Clean Coal Research Program.  In FY 12, this project was assessed a TRL of 4.

The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
