요약

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.

대표청구항

1. A device for separating carbon dioxide, the device comprising: a first separation membrane into which a combustion gas is fed;a second separation membrane into which a permeate gas of the first separation membrane is fed; anda third separation membrane into which a residue gas of the first separation membrane is fed,wherein the second separation membrane is provided with a self-recycling loop in which a portion of a permeate gas of the second separation membrane does not pass through a separation membrane other than the second separation membrane but is fed back into the second separation membrane, andwherein the third separation membrane is provided with a self-recycling loop in which a portion of a permeate gas of the third separation membrane does not pass through a separation membrane other than the third separation membrane, but the portion of the permeate gas of the third separation membrane is fed back into the third separation membrane.
