Abstract:
(EN) In a method and a system for decolorizing and deodorizing a polyhydric alcohol according to embodiments of the present invention, a mixture liquid containing a first polyhydric alcohol obtained by a separation process is prepared. The mixture liquid is subjected to a distillation treatment to preliminarily remove substances with different colors and odors to generate a pre-treatment liquid. The pre-treatment liquid is subjected to an adsorption treatment. Through a combination of the distillation treatment and the adsorption treatment, the removing efficiency of the substances with different colors and odors can be increased.
(FR) Selon des modes de réalisation, la présente invention concerne un procédé et un système de décoloration et de désodorisation d'un alcool polyhydrique, ledit procédé consiste à préparer un liquide de mélange contenant un premier alcool polyhydrique obtenu par un procédé de séparation. Le liquide de mélange est soumis à un traitement de distillation pour éliminer au préalable des substances ayant différentes couleurs et odeurs afin de générer un liquide de prétraitement. Le liquide de prétraitement est soumis à un traitement d'adsorption. La présente invention permet d'améliorer l'efficacité d'élimination de substances ayant différentes couleurs et odeurs, grâce à une combinaison du traitement de distillation et du traitement d'adsorption.
(KO) 본 발명의 실시예들에 따른 다가 알코올의 탈색 및 탈취 방법과 탈색 및 탈취 시스템에 있어서, 분리 공정에 의해 수득된 제1 다가 알코올을 함유하는 혼합액을 제조한다. 혼합액을 증류 처리를 통해 이색 및 이취 물질을 예비적으로 제거하여 전처리 액을 생성한다. 전처리 액을 흡착 처리한다. 증류 처리 및 흡착 처리의 조합을 통해 이색, 이취 물질의 제거율을 증가시킬 수 있다.
