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 16):
A distillation method, wherein a raw material of a waste stripper solution comprising a stripper and a stripped photoresist resin is introduced into a feed supply zone of a dividing wall column and separated by the dividing wall column, wherein a dividing wall is provided in an interior of the dividing wall column and the interior 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 the feed supply zone and a product discharge zone divided by the dividing wall.
