A Novel Approach To Carbon Dioxide Capture And Storage, Brett P. Spigarelli

Dissertations, Master's Theses and Master's Reports - Open

The novel approach to carbon capture and storage (CCS) described in this dissertation is a significant departure from the conventional approach to CCS. The novel approach uses a sodium carbonate solution to first capture CO₂ from post combustion flue gas streams. The captured CO₂ is then reacted with an alkaline industrial waste material, at ambient conditions, to regenerate the carbonate solution and permanently store the CO₂ in the form of an added value carbonate mineral. Conventional CCS makes use of a hazardous amine solution for CO₂ capture, a costly thermal regeneration stage, and the underground storage …
