Title:
ORGANIC SOLVENT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/167185
Kind Code:
A1
Abstract:
An organic solvent recovery system comprising a recovery device (1), a dehydration device (2), and a return device (3). The dehydration device (2) includes: a dehydration material (202) for coming into contact with a recovered solvent (113B) to thereby absorb moisture contained in the recovered solvent (113B); one or more dehydration treatment tanks (203) in which the dehydration material (202) is stored; and a discharge mechanism for supplying the recovered solvent (113B), which is separated by a separator (113), to the one or more dehydration treatment tanks (203) and discharging, from the one or more dehydration treatment tanks (203), a dehydrated solvent (E) obtained through dehydration from the recovered solvent (113B) by the dehydration material (202). When returning the recovered solvent (113B) within the one or more dehydration treatment tanks (203) to the separator (113), the return device (3) sends the recovered solvent (113B) to a recovered-solvent (113B) layer of the separator (113). This organic solvent recovery system makes it possible to discharge a dehydrated solvent from which moisture is sufficiently removed even upon restarting of the system.
