Claim 2:
3. The air separation device according to claim 1, further comprising an adsorption processing time determining unit which:
calculates a quantity of moisture and a quantity of carbon dioxide in the feed air on the basis of the temperature of the feed air introduced into the pre-purification unit, the pressure of the feed air introduced into the pre-purification unit, and the flow rate of the feed air fed to the purification portion;
calculates a moisture adsorbable time during which moisture can be adsorbed by an adsorbent, and a carbon dioxide adsorbable time during which carbon dioxide can be adsorbed by the adsorbent, from the quantity of moisture and the quantity of carbon dioxide, and the filling amount of the adsorbent in the pre-purification unit; and
determines the value of the smaller of the moisture adsorbable time and the carbon dioxide adsorbable time to be an adsorption processing time.
