Abstract
In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing at least carbon dioxide, nitrogen and water vapor, the energy utilization efficiency thereof is improved. The gas separation apparatus is constructed to include a first separation membrane 33 and a second separation membrane 34 that are made of different materials. When the first mixture gas is supplied, the first separation membrane 33 separates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membrane 34 separates water vapor that permeates through the second separation membrane 34 by allowing water vapor to permeate selectively.
