  • Carbon dioxide is recognized as one of the major substances that cause climate change, and the global number of large-scale facilities that emit more than 100,000 tons of CO 2 annually emits 7900 units and 13.5 billion tons of carbon dioxide. It accounts for 55% of the billion tons. Therefore, in order to stabilize carbon dioxide in the atmosphere, it is desirable to first collect CO 2 in a large-scale carbon dioxide emission facility.
  • This method uses solid particles instead of the liquid solvent used in conventional wet chemical cleaning to react with carbon dioxide in the flue gas to make it a stable compound, and separates pure carbon dioxide using water vapor and an additional heat source. It is a technique to reuse repeatedly and continuously. In addition, because of the fluidized bed process, the installation area is small, the heat transfer characteristics are excellent, and the operation is easy.
  • Dry Regeneration Absorption technology is characterized by almost no waste water, less corrosion problems, and can be used for a variety of inexpensive materials. In addition, it has a great potential for sustainable growth compared to other technologies in many aspects such as design flexibility, eco-friendliness, low energy regeneration, and high efficiency carbon dioxide absorption (absorption and reactivity).
  • the object of the present invention is to effectively capture the carbon dioxide contained in the flue-gas before discharging it to the atmosphere, and to be easily regenerated by an additional heat source so that it can be repeatedly used for a long period of time while continuously cycling between the two reactors for absorption and regeneration.
