Title (EN) IMPURITIES SEPARATION BY DISTILLATION
(FR) SEPARATION D'IMPURETES PAR DISTILLATION
Abstract: front page image
(EN)A distillation procedure is provided for the separation of impurities from organic materials such as glycols and glycol ethers whereby a liquid stripping component is interfaced into a distillation column with or below the organic material introduction, heat being provided by a reboiler, the stripping component and impurities being removed overhead.
(FR)L'invention concerne une procédure de distillation, permettant de séparer les impuretés de matériaux organiques, tel que les glycols et les éthers glycoliques. Un composant d'extraction sous forme liquide est introduit dans une colonne de distillation près ou en-dessous du point d'introduction desdits matériaux organiques, la chaleur étant fournie par un rebouilleur, et le composant d'extraction et les impuretés étant éliminés dans la partie supérieure de la colonne.
