Praxair, Inc. has been awarded $35 million by the US Department of Energy (DOE) to accelerate development of oxygen transport membrane (OTM) systems which can dramatically reduce the cost of oxygen for synthesis gas (syngas) production and oxy-fuel combustion.
Building on the success of work previously supported by the DOE to develop basic materials, membrane structures and process integration strategies, this grant will fund OTM equipment and systems development. Pilot-scale combustion and syngas units will be built to demonstrate performance and provide critical data for design of commercial-scale facilities.
Praxair’s OTM technology forms the basis for an advanced power cycle capable of meeting long-term DOE electricity cost targets for coal-based power plants with carbon dioxide capture. In addition, combustion applications in manufacturing and process plants that may be required to control carbon dioxide emissions would also benefit from commercialization of OTM. OTM syngas systems efficiently convert natural gas and other hydrocarbons to mixtures of hydrogen and carbon monoxide used for making chemicals and liquid fuels.
