Embodiments of the present disclosure are directed to systems and methods of removing carbon dioxide from a gaseous stream using magnesium hydroxide and then regenerating the magnesium hydroxide. In some embodiments, the systems and methods can further comprise using the waste heat from one or more gas streams to provide some or all of the heat needed to drive the reactions. In some embodiments, magnesium chloride is primarily in the form of magnesium chloride dihydrate and is fed to a decomposition reactor to generate magnesium hydroxychloride, which is in turn fed to a second decomposition reactor to generate magnesium hydroxide.
The present invention relates to methods for capturing carbon dioxide and permanently sequestering carbon dioxide in the form of Group II metal carbonates. The invention involves production of HCl by reacting steam with a material that includes a magnesium chloride hydrate. The HCl that is generated from this process is used to leach Group II mineral salts from a variety of different materials, including minerals and industrial waste materials. The leached Group II mineral salts are used to capture carbon dioxide by forming Group II mineral salt carbonates.
The present invention relates to a method for capturing carbon dioxide and sequestering the carbon dioxide as calcium carbonate. The method involves the use of an aqueous solution of magnesium hydroxide as a carbon dioxide uptake fluid. The magnesium hydroxide in the uptake fluid is produced by two distinct pathways, a forced decomposition pathway and a passive dissolution pathway. The combined use of the forced decomposition and passive dissolution pathways is a significant contributing factor to the low energy penalty of the carbon dioxide capture and sequestration method.

Methods for removing carbon dioxide and other pollutants from a gas stream are provided. The methods include obtaining hydroxide in an aqueous mixture, mixing the hydroxide with the gas stream to produce bicarbonate products or a combination of carbonate and bicarbonate products in an admixture, separating the products from the admixture, and using the products to perform ion-exchanges with one or more group-1 or group-2 salts to precipitate carbonates, wherein obtaining the hydroxide comprises obtaining a group-1 or group-2 salt; mixing the salt with acid and water, acid and steam, or acid, water, and steam to produce a protonated brine solution; and electrolyzing the protonated brine solution to produce a hydroxide; and wherein mixing the hydroxide with the gas stream comprises altering the product equilibrium to favor the production of bicarbonate products.
