    Abstract: 이산화탄소 흡수제의 열화현상을 해결하기 위해 이산화탄소(CO
    2 )가 흡수탑에서 아민계 흡수제에 흡수될 때 산소가 동시에 흡수되지 않도록, 연도가스에 포함된 산소를 흡수탑 도달 전에 제거하는 공정을 제공하고자 한다. 본 발명에 따른 이산화탄소 분리 회수 장치 및 그의 공정 방법은 촉매연소장치를 통해 연도가스 속의 용존 산소를 제거한다. 이에 따라, 연도가스가 흡수탑에 도달하기 전에 용존 산소가 제거됨으로써 흡수제 산화 작용이 방지되며, 산화 작용으로 인해 발생된 열화현상을 해결할 수 있다.

    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.
