METHODS FOR REACTIVATING PASSIVATED MINERAL RESIDUES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18527079 titled 'METHODS FOR REACTIVATING PASSIVATED MINERAL RESIDUES
Simplified Explanation
The instant disclosure sets forth a process for re-activating a mineral residue. The process includes providing a mineral residue, which includes a core and a shell around the core. In certain examples, the core comprises calcium (Ca), magnesium (Mg), or a combination thereof. The Ca and Mg is not present as elemental Ca or Mg but rather as a compound of Ca or of Mg, such as but not limited to Ca(OH) or Mg(OH). In certain examples, the shell comprises an oxide, a hydroxide, a carbonate, a silicate, a sulfite, a sulfate, a chloride, a nitrate, or nitrite, of calcium (Ca) or of magnesium (Mg), or a combination thereof. The process includes (a) fractionating the mineral residue; (b) contacting the mineral residue with an acid and fractionating the mineral residue; or (c) contacting the mineral residue with a base and fractionating the mineral residue. As a result, the mineral residue's core is exposed. In some examples, the shell is passivating and inhibits the Ca or Mg, or both, in the core from reacting with carbon dioxide (CO). By exposing the core as described herein, a mineral residue's reactivity with carbon dioxide is increased.
- The process involves re-activating a mineral residue by exposing its core through fractionation and treatment with acid or base.
- The mineral residue consists of a core containing calcium or magnesium compounds and a shell made of various compounds of calcium or magnesium.
- The shell acts as a passivating agent, preventing the core from reacting with carbon dioxide and increasing the residue's reactivity.
Potential Applications
The technology could be applied in carbon capture and storage processes, soil remediation, and enhancing the reactivity of mineral residues in industrial applications.
Problems Solved
This technology addresses the issue of low reactivity of mineral residues with carbon dioxide, which limits their potential use in carbon capture and storage applications.
Benefits
The process increases the reactivity of mineral residues with carbon dioxide, making them more effective in capturing and storing CO2 emissions. It also provides a method for re-activating mineral residues that were previously considered inert.
Potential Commercial Applications
The technology could be valuable in industries focused on carbon capture and storage, waste management, and soil remediation, offering a more efficient and environmentally friendly solution for handling mineral residues.
Possible Prior Art
One possible prior art could be the use of passivating agents in industrial processes to prevent unwanted reactions, although specific applications to re-activating mineral residues may not have been explored extensively.
Unanswered Questions
== How cost-effective is the process compared to traditional methods of re-activating mineral residues? The article does not provide information on the cost implications of implementing this technology. Further research and analysis would be needed to determine the economic feasibility of using this process on a larger scale.
== What are the potential environmental impacts of treating mineral residues with acids or bases? The environmental consequences of using acid or base treatments on mineral residues are not discussed in detail. Additional studies would be necessary to assess any potential risks or benefits to the environment associated with this process.
