Abstract: The present invention relates to a method for separating carbon dioxide from mixed gas containing the carbon dioxide and, more particularly, to a method for using an amino silane group as a mixed solvent in a carbon dioxide separation apparatus including an absorption tower and a stripping tower. The method for separating carbon dioxide using the mixed solvent of the present invention includes: a step in which a carbon dioxide-mixed solvent is supplied to an upper portion of the absorption tower and the mixed gas containing carbon dioxide is introduced to a lower portion of the absorption tower so that the carbon dioxide contained in the mixed gas is absorbed into the mixed solvent; a step in which the mixed solvent into which the carbon dioxide is absorbed is sent to a re-evaporation tank (flash tank) and the carbon dioxide is stripped by pressure difference; and a step in which the mixed solvent which passes through the re-evaporation tank is sent to the stripping tower and is heated to strip the carbon dioxide. In the method for separating carbon dioxide, an amino silane-based mixed solvent is used as the mixed solvent. The amino silane solvent of the present invention has a higher carbon dioxide absorption performance and removal efficiency than existing commercial solvents, and thus capturing costs can be saved in process application. In addition, the low volatility results in excellent safety and economic feasibility in a process operation.

Abstract: The present invention relates to a method for calculating regenerative heat of a chemical absorbent for carbon dioxide. The regenerative energy of a chemical absorbent for carbon dioxide is calculated by obtaining and calculating parameters using a device in a short term instead of obtaining test values of the regenerative energy of a chemical absorbent for carbon dioxide via process operation, calculating the current heat of the absorbent from the result of measuring reaction heat and specific heat of the absorbent in the process of measuring a combustion phenomenon before and after the reaction of the absorbent for carbon dioxide, calculating the latent heat for evaporation of a solvent, and summing all the values. The method for calculating regenerative heat of an absorbent for carbon dioxide from the sum of the latent heat for evaporation, the reaction heat for absorption and the current heat comprises the steps of: calculating the latent heat for evaporation of the absorbent for carbon dioxide; measuring the reaction heat for absorption of the absorbent for carbon dioxide; and calculating the specific heat of carbon dioxide before and after reaction in the process of measuring the heat capacity before reaction of the absorbent for carbon dioxide and the heat capacity after reaction of the absorbent for carbon dioxide in a state of being completely saturated with carbon dioxide, and calculating the current heat therefrom.
