DIVIDING WALL COLUMN FOR PRODUCING HIGH-PURITY NEOPENTYL GLYCOL, AND MANUFACTURING METHOD USING SAME |
| 摘要 |
The present invention relates to a dividing wall column for producing high-purity neopentyl glycol, and to a method for distilling the neopentyl glycol. By using only one column, the dividing wall column has the same effect as when using two columns. Thus, energy and equipment costs may be reduced in the production of the high-purity neopentyl glycol as compared to a conventional process apparatus. |
