<p>PROBLEM TO BE SOLVED: To provide a vapor recovery apparatus capable of attaining efficient apparatus operation, by shortening a desorption processing time of ordinary time, without reducing the recovery effect of a fuel vapor component.SOLUTION: A plurality of adsorption tanks 21 for storing an adsorbent for adsorbing and separating the fuel vapor component from gas including fuel vapor, are provided as an adsorption tank group, and in cargo unloading work of a volatile fuel liquid to a liquid storage tank, only the adsorption tank of the required number for adsorbing and recovering its fuel vapor component, is used among a plurality of adsorption tanks 21-m as the adsorption tank group for adsorbing and recovering the fuel vapor component from the gas including the fuel vapor discharged from the liquid storage tank.</p> |
