Analytical Solution of Groups
Vapor Liquid Equilibrium Calculation by ASOG
Lecture note of Dr. Hiroshi Yamamoto for Yokohama National University (YNU)
To calculate Vapor Liquid Equilibrium, it need activity coefficients and vapor pressure scheme like Antoine equation. ASOG calculate activity coefficients. And this Program estimate vapor pressure from Pirika Neural Network method and do not use Antoine Parameters.
If you are lucky enough your browser support old JAVA and proper setting of JAVA option, you will see the window like below. Draw 2 molecles and push Calc. mol. Info. button, then program analyze molecular structure and estimate properties that need to calculate vapor pressure. Then Calc. ASOG button will appear. This button will calculate activity coefficients from Group Pair. After all the calculation is finished, the figure will appear.
You can choose several figure with radio button.
Liquid Composition-Boiling point Graph
Liquid Composition-Activity Coefficient Graph
If one of Solvent equal to water then check x Mol
You can calculate hydrocarbons, Alcohol, Ester, Carboxylic Acid , Keton only.
If you can not see this window, please give up this old JAVA verson. (This Applet is still running with Mac with FireFox browser. 2011.11.15)
