Commentary: Ex Situ Aqueous Mineral Carbonation
CO2 conversion to calcium and magnesium carbonates has garnered considerable attention since it is a thermodynamically downhill pathway to safely and permanently sequester large quantities of CO2. This seminal work performed at The National Energy Technology Laboratory in Albany (NETL-Albany) reports the conversion of calcium-and magnesium-bearing silicate minerals, such as olivine [(Mg, Fe)2Si...
متن کاملIntegration of CO2 Capture and Mineral Carbonation by Using Recyclable Ammonium Salts
A new approach to capture and store CO(2) by mineral carbonation using recyclable ammonium salts was studied. This process integrates CO(2) capture with mineral carbonation by employing NH(3), NH(4)HSO(4), and NH(4)HCO(3) in the capture, mineral dissolution, and carbonation steps, respectively. NH(4)HSO(4) and NH(3) can then be regenerated by thermal decomposition of (NH(4))(2)SO(4). The use of...
متن کاملFactors Affecting Ex-Situ Aqueous Mineral Carbonation Using Calcium and Magnesium Silicate Minerals
Carbonation of magnesiumand calcium-silicate minerals to form their respective carbonates is one method to sequester carbon dioxide. Process development studies have identified reactor design as a key component affecting both the capital and operating costs of ex-situ mineral sequestration. Results from mineral carbonation studies conducted in a batch autoclave were utilized to design and const...
متن کاملThermodynamic quantities of surface formation of aqueous electrolyte solutions: IX. Aqueous solutions of ammonium salts.
The properties of aqueous ammonium salt solutions at the air/water surface are presented. By comparison of the properties of ammonium halides solutions with those of sodium halide, we note a close similarity, which indicates that the increments in surface tension may be explained in relation to the hydration enthalpy of anions. We find that the behaviors of the salts with nitrate anions which a...
