Abstract

This study was performed to recycle Propylene Glycol Monomethyl Ether Acetate (PGMEA) from Liquid Crystal Display (LCD) industry emission as a waste organic solvent by using a multistage distillation column and tried to decide optimum reflux ratio. From the final experiment result, it was confirmed ; in case the sample A, the PGMEA purity is more than 98% and the moisture is less than 0.05%, on the other hand, in case the sample B, the PGMEA purity is more than 95% when the reflux ratio is 6 and the moisture is less than 0.01% (Refer to Table 1 for the contents of sample A and B). These values means fine level which can be adapted in the LCD manufacture, requiring more than 90% common purity of recycling level.
