  • Publication number: 20250092595
    Abstract: A laundry treating apparatus includes a 2-tank structure including a distillation tank and a washing tub. The laundry treating apparatus includes the washing tub that defines an inner space configured to receive laundry, the distillation tank configured to store liquid carbon dioxide, a compressor configured to receive gaseous carbon dioxide evaporated from the liquid carbon dioxide in the distillation tank, the compressor being configured to discharge the gaseous carbon dioxide, a cooler configured to cool the gaseous carbon dioxide discharged from the compressor and to supply the liquid carbon dioxide to the washing tub, and a controller configured to perform a control method. In some cases, a laundry treating apparatus includes a 3-tank structure including a storage tank, a washing tub, and a distillation tank.

  • Patent number: 9487626
    Abstract: This invention relates to a method of fixing carbon dioxide by condensation polymerization in an acidic aqueous medium, thereby increasing fixation efficiency and remarkably reducing the volume of generated material compared to conventional carbon dioxide fixation methods; a polymer material prepared by the method; and a method of recovering carbon therefrom. According to the current invention, the method of fixing carbon dioxide is characterized by introducing carbon dioxide pressurized to a pressure higher than atmospheric pressure into a reactor containing a acidic aqueous medium, so that carbonic acid resulting from dissolving carbon dioxide is made into a polymer material by condensation polymerization, thereby fixing carbon dioxide, and heating the polymer material so as to recover carbon.

  • Patent number: 8506809
    Abstract: Disclosed are a method and an apparatus for production of bio-gas, capable of improving quality of a raw material to be fed thereto. Among the raw material, a part free from inhibitory materials is directly introduced an anaerobic digestion reactor while the other part containing the inhibitory materials is introduced into a first solid-liquid separator and separated into a solid-phase material free from the inhibitory materials and a liquid-phase material containing the inhibitory materials. The solid-phase material in the first solid-liquid separator is fed to the anaerobic digestion reactor after hydrolysis. A liquid waste in the anaerobic digestion reactor and a liquid-phase material in the first solid-liquid separator are concentrated by a sludge concentrator.
