Abstract
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 mineralizatio…
