Title (EN) DIVIDING WALL COLUMN FOR PRODUCING HIGH-PURITY NEOPENTYL GLYCOL, AND MANUFACTURING METHOD USING SAME
(FR) COLONNE À PAROI DE DIVISION POUR PRODUIRE DU NÉOPENTYLGLYCOL DE GRANDE PURETÉ ET SON PROCÉDÉ DE FABRICATION
(KO) 고순도 네오펜틸글리콜 생산을 위한 분리벽형 증류탑 및 이를 이용한 제조방법
Abstract: front page image
(EN)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.
(FR)La présente invention concerne une colonne à paroi de division pour produire du néopentylglycol de grande pureté et un procédé de distillation du néopentylglycol. En utilisant une seule colonne, la colonne à paroi de division présente le même effet que lorsque deux colonnes sont utilisées. Ainsi, les coûts en énergie et en appareillage peuvent être réduits dans la production du néopentylglycol de grande pureté par comparaison avec un appareil de traitement classique.
(KO)본 발명은 고순도 네오펜틸글리콜 생산용 분리벽형 증류탑, 및 네오펜틸글리콜 증류방법에 관한 것이다. 본 발명의 분리벽형 증류탑은 1기의 증류탑으로 2기의 증류탑의 효과를 가지므로, 고순도 네오펜틸글리콜을 생산하는데 있어서 종래의 공정 장치에 비해 에너지 절감 효과는 물론 장치의 설비비도 줄일 수 있는 효과가 있다.
