Computer Graphics에 의한 3성분계 Wilson, NRTL 및 UNIQUAC 방식을 이용한 VLE 추정방식의 비교 = Comparison of Methods of Estimating VLE by Means of the Wilson, NRTL, UNIQUAC Equations for Ternary Systems by Computer Graphics

다국어 초록 (Multilingual Abstract)

The purpose of this study is to estimate VLE by means of the Wilson, NRTL, UNIQUAC equations and to compare with these three methods for two ternary systems: ethanol-benzene-cyclohexane, cyclohexanone-cyclohexanol-phenol, by the computer graphic technology. The temperatures and compositions of two systems were estimated by means of three TPTT equations. Isothermal lines of these two ternary systems were graphically illustrated from these estimated values and the reported experimental values.
As a result of the analysis of the parameters and computer graphics, these parameter pairs changing with respect to the temperature and composition of the solutions. From the result of plotting the parameter pairs, A_12, vs, A_21, a locus contour between two parameters is observed, therefore numerous number of roots to satisfy these TPTT equations are found. These phenomena is nearly identical with the previously reported results that there are some correlation between these parameter pairs.
