Abstract

Due to the rising cost of energy, new separation processes based on extraction are becoming more attractive than before. Thus, the need for calculating and predicting liquid-liquid equilibria(LLE) compositions has very much increased. The purpose of this study is to determine the binodal curves, tie line, plait point, distribution and selectivity for the ternary systems of 2-propanol-water with methyl ethyl ketone, methyl isobutyl ketone, ethylacetate, toluene and o-xylene as solvents at $25^{\circ}C$. And those tie line data were used to examine thermodynamic consistency. The experimental tie line data were correlated with NRTL and UNIQUAC models.

에너지 비용의 상승에 따라 추출의 기본원리를 둔 새로운 분리공정에 대한 연구가 많이 진행되고 있으며, 이에 따라 액-액평형 조성의 계산 및 예측에 대한 필요성이 매우 증가하고 있다. 본 연구에서는 공비혼합물을 형성하는 2-propanol 수용액에 용매로서 methyl ethyl ketone, methyl isobutyl ketone, ethylacetate, butylacetate, toluene 및 o-xylene을 첨가한 삼성분계에 대하여 $25^{\circ}C$에서 용해도곡선, tie line, plait point, 분배계수와 선택도를 실험을 통해 구하였다. Tie line 데이터의열역학적 건전성을 확인하였으며 실험값을 NRTL 및 UNIQUAC 모델식으로 구한 계산값과 비교하였다.
