초록

분리공정에서 성공적인 정류탑의 설계에는 정확한 기-액평형치가 이용된다. 2성분 ethanol-1-propanol계에 대하여 정온하, 즉 50, 55, 60, 65, 70, 75 및 80 ℃에서의 기-액평형치를 측정하고, 그 측정치를 이용하여 기-액평형치를 추산하는 추산식을 이끌어 내었다. 측정치와 추산치를 비교 검토한 결과 기상조성의 몰분율은 ±0.0014의 오차범위 내에서 잘 일치하고 있다.

Successful design of distillation columns in a separation process depends on the availability of accurate vapor-liquid equilibrium data. For the binary of ethanol-1-propanol mixture, isothermal vapor-liquid equilibrium data were measured at temperatures of 50, 55, 60, 65, 70, 75, and 80 ℃. An empirical relation to predict vapor-liquid equilibrium data was obtained from the above measured data. The predicted values were compared with the measured ones, and they were found to be in a good agreement with accuracy of ±0.0014.

Keywords:1-propanol;isothermal data;vapor-liquid equilibrium;separation process
