Disclosed is a hybrid system of carbon dioxide compact separation membrane and carbon recycling for an urban power plant for effluent carbon dioxide concentration control, including a blower into which an exhaust gas is input and which distributes the exhaust gas, a photo-culture process unit which receives the exhaust gas from the blower, performs a photo-culture process using microalgae, and discharges a first treatment gas, a mixing tank into which the exhaust gas supplied from the blower and the first treatment gas are input, a separation membrane process unit which receives a second treatment gas mixed in the mixing tank, and separates a third enriched gas from the second treatment gas using a plurality of separation membranes, a mineralization reaction unit which mineralizes carbon dioxide using the third enriched gas separated in the separation membrane process unit and discharges a third treatment gas to the mixing tank, a sensor unit which measures a carbon dioxide concentration discharged from each process using a plurality of sensors, and a control unit which controls operations of the photo-culture process unit, the separation membrane process unit and the mineralization reaction unit according to a carbon dioxide content of the inflow exhaust gas.

Hybrid system of carbon dioxide compact membrane separation and carbon recycling for urban power plant for effluent carbon dioxide concentration control

The present invention provides a system for capturing and recycling carbon dioxide in an exhaust gas, which includes a COcapture unit into which an exhaust gas containing COis input, and which captures the COas a high concentration enriched gas and separates a first treatment gas; a mineralization process unit which mineralizes the COafter receiving the high concentration enriched gas captured in the COcapture unit and discharges a second treatment gas; a mixing tank which receives the first treatment gas and the second treatment gas and mixes them so that the contained COhas a predetermined concentration; a photo-culture process unit which receives the resulting third treatment gas from the mixing tank to perform a photo-culture process using microalgae; and a control unit which controls the flow rates and the COcontents of the gases supplied and discharged to/from the COcapture unit, the mineralization process unit, the mixing tank and the photo-culture process unit.
