  • Patent number: 10818953
    Abstract: An apparatus and process are provided for electricity production and high-efficiency trapping of carbon dioxide, using carbon dioxide within combustion exhaust gas and converging technologies associated with a carbon dioxide absorption tower and a generating device using ions which uses a difference in concentration of salinity between seawater and freshwater. It is expected that enhanced electrical energy production efficiency, an effect of reducing costs for the operation of a carbon dioxide trapping process, and electricity production from carbon dioxide, which is a greenhouse gas, can be simultaneously achieved by increasing the difference in concentration using an absorbent for absorbing carbon dioxide.

  • Patent number: 10561976
    Abstract: A carbon dioxide capturing apparatus and process uses a self-generating power means that uses carbon dioxide in combustion exhaust gas through the convergence of a carbon dioxide absorption tower. The capturing apparatus and process also relies on ionic generator associated technology using a concentration difference between seawater and freshwater. The capturing apparatus and process result in increased production efficiency for electric energy and reduced costs for a carbon dioxide capturing process by increasing a concentration difference using an absorbent liquid for absorbing carbon dioxide and, at the same time, electricity is obtained through carbon dioxide which is a greenhouse gas.

  • Patent number: 9713790
    Abstract: Disclosed are a compound including an oxalate, a carbon dioxide absorbent including the same, a method of preparing the carbon dioxide absorbent and a method of removing carbon dioxide, which may overcome issues of high recycling energy and low absorptivity of a conventional carbon dioxide absorbent to considerably reduce recycling energy and absorb a greater amount of carbon dioxide per unit absorbent, so that a size of a carbon dioxide absorption tower may be reduced and a less amount of recycling energy may be used, contributing to a substantial decrease in device manufacture costs and management costs.

  • Patent number: 9242205
    Abstract: The present invention relates to a carbon dioxide absorbent, and more particularly, to an alkali carbonate-based carbon dioxide absorbent containing added sterically hindered cyclic amines, and to a method for removing carbon dioxide using same. By adding sterically hindered cyclic amines to an alkali carbonate material, the rate of carbon dioxide absorption is increased, renewable energy is reduced, and salt production and phase separation do not occur.

  • Patent number: 8883891
    Abstract: The present invention relates to an ionic liquid-polymer gel membrane with improved gas permeability, and a preparation method thereof, and more specifically, to a membrane prepared to allow an ionic liquid to be dispersed in a polymer gel, thereby improving gas permeability. Particularly, the present invention relates to an ionic liquid-polymer gel membrane wherein membrane selectivity and permeability exceed an upper bound by increasing the amount of dispersed ionic liquid, and a preparation method thereof. The preparation method of the membrane for separating a specific gas from a mixture gas according to the present invention comprises the following steps of: mixing a polymer, an ionic liquid and PC as a solvent to prepare a mixture solution; and drying the mixture solution to remove the solvent from the mixture solution. In addition, the polymer is polyvinylidene fluoride-hexafluoropropyl copolymer (PVdF-HFP), and the ionic liquid is 1-ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]).

  • Patent number: 8840806
    Abstract: Provided is an absorbent for capturing carbon dioxide. The absorbent may include an amino acid with multiple amine groups and an alkali-metal hydroxide mixed with the amino acid and thus, may increase an absorption capacity for carbon dioxide. When a sterically hindered effect is induced to the amino acid with multiple amine groups, the absorption capacity for carbon dioxide may increase and heat of absorption reaction may decrease and thus, energy consumed for regeneration of an absorbent may be reduced. The absorbent for capturing carbon dioxide may include amino acid with multiple amine groups and the metal hydroxide, and may provide a functional group around the amine groups to cause an sterically hindered effect and thus, the absorption capacity for carbon dioxide and an carbon dioxide absorption rate may increase, and the capital cost for a carbon dioxide capturing process and an operating cost may be significantly reduced.
