<P>PROBLEM TO BE SOLVED: To provide a device capable of stably removing moisture from a large amount of organic solvent basically without needing replacement of adsorbent by attaining continuous dehydration of the organic solvent. <P>SOLUTION: The solvent dehydration device is provided with a solvent dehydration step of introducing a moisture-containing organic solvent to an adsorption tank through a treatment object organic solvent inlet path and bringing it into contact with an absorbent filled in the tank, thereby adsorbing and removing the moisture contained in the organic solvent; and a desorption step of desorbing the moisture adsorbed in the adsorbent by circulating and introducing an inert gas to the adsorbent. The device includes: inert gas regeneration equipment for performing regeneration treatment on inert gas used in the desorption step; and an inert gas circulation path for introducing the inert gas regenerated in the inert gas regeneration equipment to the adsorption tank and returning inert gas discharged from the adsorption tank to the inert gas circulation regeneration equipment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
