PRO/II 를 이용한 에탄올-몰 공비혼합물의 공정모사 = Process simulation of ethanol-water azeotropic mixture by using PRO/II simulator

다국어 초록 (Multilingual Abstract)

In this research, we found the optimal condition of the process that separates the mixture to water-ethanol, using Simulation Science Co.'s PRO/II.
The water-ethanol mixture has the azeotrophic point at 78.15℃, 1atm, 95.5wt%. This mixture having azeotropic point is called azeotrope. It is impossible to make a highly pure ethanol by using a ordinary distillation.
Therefore, it is necessary to use a special distillation, such as azeotropic distillation, to makes a highly pure ethanol from water-ethanol azeotrope by breaking or shifting this azeotrope's azeotropic point to input entrainer in this zerotrope. It is important to choose a suitable the entrained.
