Abstract
혼합용액의 분리공정에서 증류탑 설계에 필요한 기-액 평형에 관한 연구로서 2성분 1-propanol-propylacetate계에 대하여 감압하 즉, 100, 200, 300, 400, 500, 600, 700 및 760 Torr에서의 기-액 평형치를 측정하고, 그 측정치를 이용하여 기-액 평형치를 추산하는 추산식을 이끌어 내었다. 측정치와 추산치를 비교 검토한 결과 ±0.0019의 적은 오차 범위내에서 잘 일치하고 있다.
For the binary system of 1-propanol-propylacetate mixture vapor-liquid equilibrium data, which are the necessary ones for the design of the distillation columns in separation process, are measured at subatmospheric pressure of 100, 200, 300, 400, 500, 600, 700 and 760 Torr. An empirical relation to predict vapor-liquid equilibrium data is obtained from above measured data. The predicted values are compared with the measured ones to be in a good agreement within accuracy of ±0.0019.
