Title: Kyungsun Song’s Patents in Environmental and Materials Processing.
Introduction
Kyungsun Song is an inventor based in Daejeon, South Korea. His patent work addresses methods for processing industrial and construction waste, including calcium carbonate production and asbestos detoxification. Song is associated with the Korea Institute of Geoscience and Mineral Resources and has 2 patents listed in the information provided.
Latest Patents
Song’s listed patents describe approaches to recovering useful materials and reducing environmental hazards.
- Method of Preparing Calcium Carbonate Using Direct Carbonation Reaction. This method dissolves fuel gas desulfurization gypsum in an ammonia solution, then introduces carbon dioxide to initiate carbonation. After filtering, the solution is left stationary so calcium carbonate can precipitate, followed by another filtering step.
- Method of Detoxifying Asbestos Contained in Waste Slate and Detoxified Asbestos Obtained Through the Same. This method uses hydrochloric acid to dissolve and remove limestone from pulverized waste slate, concentrating the asbestos. The concentrated material is mixed with oxalic acid and treated at a low temperature. The patent also describes detoxified asbestos containing recrystallized magnesium oxalate in rhombohedral or amorphous form.
Career Highlights
Song’s listed inventions focus on practical treatment of industrial byproducts and hazardous waste. One patent describes producing calcium carbonate from fuel gas desulfurization gypsum, while the other presents a process for detoxifying asbestos in waste slate. Both inventions involve chemical processing and material transformation.
Collaborations
Song’s listed coworkers include Young-Nam Jang and Soo-Chun Chae. The provided information identifies his institutional affiliation as the Korea Institute of Geoscience and Mineral Resources.
Conclusion
Kyungsun Song’s patent portfolio, as described here, centers on environmental processing methods that recover calcium carbonate from industrial gypsum and detoxify asbestos-containing waste slate.
