NITROGEN-SELECTIVE MEMBRANE FOR CARBON CAPTURE
Impact/Purpose:
The proposed research aims at reducing the emissions of carbon dioxide (CO2), a greenhouse gas, from the post-combustion flue gas stream in coal power plants.
Description:
Dense membrane technology will be tested and applied under conditions that optimize the separation of N2 from CO2 from post-combustion flue gas. This membrane technology will help in retrofitting existing coal-fired power plants so as to comply with emission regulations.

Project Information:
Approach
:The project will involve both theoretical modeling and experiments. A dense membrane technology will be applied to a post-combustion flue gas stream to separate nitrogen gas (N2) from CO2. N2 typically comprises about 77% and CO2 about 13% of the stream. The membrane is comprised of vanadium and niobium and will selectively separate N2 from the flue gas stream by the catalytic dissociation of the N2 molecule into two atoms of nitrogen. Nitrogen then diffuses through membrane and leaves the CO2 behind for further processing so as to not be directly emitted into the atmosphere.
Cost
:$10,000.00
