| titleOfInvention | Recovery system of the organic solution from the waste result solution of polyimide production process |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously recovering organic solvents generated after manufacturing a semiconductor and a polyimide film for a flexible display. The present invention relates to a reactive waste solvent filtration device (S1) for recovering a reactive waste solvent composed of an organic, aqueous and solid particle mixture generated in a polyimide synthesis process for a semiconductor or a flexible display to filter solid particles contained therein, A reactive distillation apparatus (S3) for esterifying the acetic acid contained in the reaction waste solvent by adding alcohol in a gaseous state to the filtered reaction waste solvent, and a reactive distillation apparatus (S4) for removing unreacted acetic acid and impurities in the adsorbent column through an adsorption column, and fractionation distillation means for recovering high purity organic solvent by fractional distillation to remove impurities remaining after treatment of the adsorption column, A continuous recovery device for recovering an organic solvent generated after manufacturing a semiconductor and a polyimide film for a flexible display, Provided. Therefore, the continuous high purity refining of organic solvents which are dependent on incineration disposal according to the present invention enables the recycling of the solvent generated in the continuous polyimide chemical reaction, resulting in cost reduction as well as a dramatic increase in polyimide productivity by continuous re- And the like. |
