Praxair has signed a multi-year agreement with Foster Wheeler North America Corp. to pursue clean coal demonstration projects, with the US industrial gases company providing the upstream oxygen supply facilities and downstream CO2 capture and gas processing technologies and equipment.

The companies revealed that Foster Wheeler will develop and supply steam generators using oxy-coal combustion technology that can be installed in new or existing coal-fired power plants. The company, a subsidiary of Foster Wheeler Ltd, expects that its first application of oxy-coal combustion technology would involve its circulating fluidised-bed steam generators.

Praxair will supply the oxygen supply facilities, applying its design, engineering and construction expertise in building large cryogenic air separation plants that produce the large volumes of oxygen necessary for clean-coal projects. The firm will also provide the downstream CO2 capture and gas-processing technologies and equipment.
