A DIVIDING WALL COLUMN AND A METHOD OF PURIFYING NEOPENTYL GLYCOL USING THE SAME

摘要

The present invention relates to a dividing wall column and a method of purifying neopentyl glycol using the same. More specifically, it relates to a dividing wall column which can purify crude products including neopentyl glycol with high purity and a method of purifying neopentyl glycol using the same. According to the dividing wall column of the present invention and the method of purifying neopentyl glycol using the same, it is possible to purify the crude product including low content of neopentyl glycol and high content of high-boiling components with high purity, and the energy consumption can be reduced, compared to conventional ways.
