She has made significant contributions to the field of environmental technology, particularly in the area of carbon dioxide separation from flue gases. Her innovative methods aim to address pressing environmental challenges related to carbon emissions.
Latest Patents
Sheila Hedges holds one patent that outlines two methods for the separation of carbon dioxide from flue gases. The first method utilizes a phase-separating moiety dissolved in an aqueous solution of a basic moiety to capture carbon dioxide. The second method employs a phase-separating moiety as a suspended solid in an aqueous solution of a basic moiety for the same purpose. The first method takes advantage of the surface-independent nature of the CO absorption reactions in a homogeneous aqueous system. The second method also provides permanent sequestration of carbon dioxide. Both methods incorporate the kinetic rate enhancements of amine-based scrubbing while eliminating the need to heat the entire amine solution, which consists of 80% water, in order to regenerate and release CO. Additionally, both methods leverage the low-regeneration temperatures of CO-bearing mineral systems such as sodium carbonate/sodium bicarbonate and potassium carbonate/potassium bicarbonate.
