CARBON DIOXIDE SEPARATION AND CAPTURE APPARATUS AND METHOD OF CONTROLLING OPERATION OF CARBON DIOXIDE SEPARATION AND CAPTURE APPARATUS

摘要

In a carbon dioxide separation and capture apparatus according to an embodiment, a control device calculates a flow rate range of a carbon dioxide gas based on the concentration of the carbon dioxide gas and an output range of a blower. The control device determines a flow rate of the carbon dioxide gas in which the sum of energy is the least based on relationships, corresponding to a preset target amount of carbon dioxide gas to be captured, between a flow rate of the carbon dioxide gas, and sum of energy obtained by summing the amount of heat to be supplied by a heating medium from the external, power of the blower and power of a pump. The control device controls output of the blower, an opening degree of the first flow rate control valve, and an opening degree of the second flow rate control valve.
