  • Patent number: 11065572
    Abstract: Disclosed is a system for integrally treating a composite waste gas including nitrogen oxides (NOx and N2O), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorinated compounds (PFCs). The system includes a first wet processor configured to wash and adsorb dust including gases, SOx, and ash dissolved in water, a decomposing reactor configured to receive waste gas processed in the first wet processor and process nitrogen oxides (NOx and N2O), fluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorinated compounds (PFCs) in the waste gas, and a second wet processor configured to receive the waste gas processed in the decomposing reactor and wash and adsorb the received waste gas. The system can efficiently treat a large amount of composite waste gas.
    Type: Grant

  • Patent number: 10557000
    Abstract: A method for preparing an oblate polymer particle from a spherical polymer particle includes squeezing a polymer film including spherical polymer particles. A pair of polymer sheets are used to uniformly deform the film. With this method, more uniform oblate particles may be prepared, and a yield rate thereof may be improved.
