dc.description.abstract"Air capture" is a proposed technology that could enable industrial-scale extraction of atmospheric carbon dioxide, and could offer benefits as a cost-effective tool to manage the risks associated with climate change. Previous work has quantified the C02 absorption performance but has not examined energy requirements associated with competing absorber geometries. Through analytical work, I have calculated C02 flux values for absorption into strong sodium hydroxide solutions, and I have measured fluxes experimentally in a range of conditions and geometries and have observed typical C02 absorption fluxes of ~20 ?mol/m2s, in rough agreement with previous literature. Through simulation, I have demonstrated that contactor geometries which induce turbulent air-side transport of C02 in order to increase absorption do so at an expense of increased energy dissipation, and that current structured packing materials may introduce too much turbulent mixing making them sub-optimal for air capture applications.

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
