Abstract:
By using the distillation device of the present application, energy loss occurring in a purification process of a solution including a waste stripper and a stripped photoresist resin used in a stripping process of a photoresist can be minimized and the installation cost of the distillation device can be reduced compared to the case in which dual distillation columns are used, thereby increasing the economic feasibility of a process.

Claim (Index 1):
A distillation device, comprising a condenser, a reboiler, and a distillation column, a dividing wall being provided in an interior of the distillation column,\n wherein an interior of the distillation column is divided into a column top zone; a column bottom zone; and a dividing wall zone that is present between the column top zone and the column bottom zone and contacts the column top zone and the column bottom zone, the dividing wall is located in the dividing wall zone, and the dividing wall zone is divided into a feed supply zone and a product discharge zone divided by the dividing wall, a raw material of a waste stripper solution comprising a stripper and a stripped photoresist resin is introduced into the feed supply zone and the introduced raw material is respectively separated into and discharged as a product stream, a column bottom stream, and a column top stream, the column bottom stream is discharged from the column bottom zone and a portion of the column bottom stream is refluxed into the column bottom zone via the reboiler, the column top stream is discharged from the column top zone and a portion of the column top stream is refluxed into the column top zone via the condenser, and the product stream is discharged from the product discharge zone.
