  • Patent number: 12351527
    Abstract: A method of forming a concrete product includes directly capturing CO2 from a gas source, the capturing comprising contacting the gas source with an absorption solution having a solvent and a solute, wherein the solvent and/or the solute are capable of reacting with CO2 to form an anionic compound, adjusting the pH of the absorption solution electrochemically to less than about 7 to release the CO2 as a concentrated vapor containing CO2, collecting the concentrated vapor containing CO2, regenerating the solvent and/or the solute, and optionally collecting the regenerated solvent and/or solute; flowing the concentrated vapor containing CO2 through a gas processing unit to adjust at least one of a temperature, a relative humidity, or a flow rate of the concentrated vapor containing CO2; and contacting the concentrated vapor containing CO2 with a concrete component.

  • Publication number: 20250091962
    Abstract: Provided herein are active flow-through carbonation curing systems useful for contacting carbon dioxide (CO2) gas streams with concrete materials under ambient pressure. This contacting causes a carbonation reaction in which CO2 forms materials, such as, but not limited to, calcium carbonate (CaCO3). The methods include, but are not limited to, contacting a conditioned flue gas containing CO2 inside of a carbonation chamber with green bodies or concrete components in which flue gas properties such as temperature, relative humidity, flow rate, and flow direction, are self-adjusted during the curing process based on a self-sensing instrumentation system inside a curing chamber and carbonation kinetic regression model. This system improves CO2 capture efficiency and material performance while reducing processing energy.
