Gas Technology Institute (GTI) will develop a membrane separation technology to recover water vapor from power plant flue gas based on their patented Transport Membrane Condenser (TMC) technique.  The implementation of this technology would reduce power plant freshwater withdrawal and consumption.

This three-phase project will: (1) evaluate the membrane and develop the two-stage TMC design concept for optimum water and heat recovery from power plant flue gas; (2) design, build, and test the pilot-scale TMC to evaluate its overall performance on flue gas from an existing 3 million-British Thermal Unit/hour industrial boiler at GTI; and (3) test the pilot-scale TMC on a power plant slipstream at an Alliant Energy power plant and develop a scale up design and commercialization plan.
