  • Publication number: 20130276631
    Abstract: This invention relates to a method for removing carbon dioxide in an exhaust gas utilizing seawater, and to apparatuses for removing carbon dioxide by the method. The method includes producing a concentrated seawater having an increased concentration of salt by utilizing a reverse osmosis membrane method, producing an ammonia-saturating concentrated seawater by blowing ammonia into the concentrated seawater, contacting a non-heated exhaust gas with the ammonia-saturating concentrated seawater such that carbon dioxide is absorbed in the ammonia-saturating concentrated seawater, collecting a sediment of sodium hydrogen carbonate, and collecting ammonium chloride from a solution comprising the ammonium chloride produced by absorption of the carbon dioxide in the ammonium-saturating concentrated seawater.

  • Patent number: 8486182
    Abstract: According to one embodiment, a method for removing carbon dioxide in an exhaust gas utilizing seawater includes: blowing ammonia into seawater to produce ammonia-saturated seawater; contacting an exhaust gas under a state of non-heat with the ammonia-saturated seawater so that carbon dioxide in the exhaust gas is absorbed in the ammonia-saturated seawater; and splaying a solution containing sodium hydrogen carbonate and ammonium chloride which are produced through absorption of the carbon dioxide by the ammonia-saturated seawater utilizing pressure of the exhaust gas while cooling the solution utilizing heat of evaporation of a solvent of the solution so as to settle out and recover the sodium hydrogen carbonate and the ammonium chloride.
