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.
