摘要： This invention relates to a device for separating carbon dioxide that includes a self-recycling loop, and to a method of separating carbon dioxide, which serve to effectively separate carbon dioxide from a combustion gas using a separation membrane provided with the self-recycling loop. This invention adopts a self-recycling loop in which the residue gas passing through a specific separation membrane is introduced into another separation membrane and in which a permeate gas passing through the specific separation membrane is introduced back into the specific separation membrane. Accordingly, the concentration of carbon dioxide in the feed gas of the specific separation membrane is increased, which increases the concentration of the permeate gas to thus improve the separation performance of the separation membrane, thereby separating high-purity carbon dioxide.

摘要： The present invention relates to a low-temperature membrane separation device and method for capturing carbon dioxide at a high concentration, in which a gas mixture is passed through a membrane unit to thus separate carbon dioxide. The membrane unit includes a membrane for capturing carbon dioxide and is connected to a feed gas line, a retentate gas line and a permeate gas line. The method includes a first separation step of passing the gas mixture through a first membrane unit and a second separation step of passing the permeation gas, which is discharged to the permeate gas line connected to the first membrane unit, through a second membrane unit. The second separation step is performed at a temperature that is lower than a temperature at which the first separation step is performed.
