  • Method for operating adsorption device
    Patent number: 12064723
    Abstract: In a method of operating an adsorption apparatus including a plurality of adsorption beds each packed with a physical adsorbent, when an adsorption step is performed in a part of the adsorption beds and another adsorption bed is to be regenerated, after the adsorption target component adsorbed on the physical adsorbent is desorbed, a gas for cooling is caused to flow through the another adsorption bed so that the another adsorption bed is cooled until an outlet temperature of the another adsorption bed reaches a temperature set in advance. Further, the cooled adsorption bed stands by for switching to the adsorption step while a gas for standby for maintaining a cooled state is caused to flow through the cooled adsorption bed.
