Abstract

Recently, an understanding of new sources of liquid hydrocarbons such as bio-ethanol is economically very important. Successful design of distillation columns in a separation process depend on the availability of accurate vapor-liquid equilibrium data. For the binary system of Ethanol/3-methyl-l-butanol mixture, isothermal Vapor-liquid equilibrium data were measured at temperature of 50, 55, 60, 65, 70, 75 and $80^{\circ}C$. An empirical relation to predict Vapor-liquid equilibrium data was obtained from the above measured data. The predicted values are compared with the measured ones to be in a good agreement within accuracy of ${\pm}0.0005$, ${\pm}0.0022$.

청정대체 에너지로 관심이 고조되고 있는 바이오 에탄올의 경제적 생산은 고유가 시대에 있어 매우 중요하다. 분리공정에서 성공적인 정류탑의 설계에는 정확한 기-액 평형치가 이용된다. 2성분 Ethanol/3-methyl-1-butanol 계에 대하여 정온하 즉 50, 55, 60, 65, 70, 75 및 $80^{\circ}C$에서 2성분 기-액평형측정치를 측정하고, 그 측정치를 이용하여 기액평형치를 추산하는 추산식을 이끌어 내었다. 측정치와 추산치를 비교 검토한 결과 ${\pm}0.0005$, ${\pm}0.0022$의 범위 내에서 잘 일치함을 확인하였다.
