        The organic solvent is used in many industries. Generation of waste organic solvent is continuously increasing. The 2009 years total domestic production organic solvent is in use 21% total designation waste production with 682 thousand tons. processes of a waste organic solvent and management issue is increasing in advanced countries. To resolve this problem, evaluate the characteristics of a batch distillation column purification to propose alternative. Therefore, this study compares a refinement recovery characteristic of simple distillation and 10-stage distillation tower. It grasps a characteristic regarding refinement recovery of the waste organic solvent (Propylene Glycol Mnomethyl Ether Acetate)PGMEA which occurred at LCD processes through study of a hundred steps of distillation tower. In this study, the evaluate scale-up separation characteristics difference using 10-stage and 100-stage batch distillation column. The actual process of making a demonstration plant appointed by using waste organic solvents of high purity propose a method for recycling.
