Aspen query azeotrope problem
Thread Content
Cyclohexane-propenol uses the NRTL equation in Aspen V8.2. Through binary phase diagram analysis, it is felt that there is an azeotrope. Through Azeotrope search, there is no azeotrope. It is obtained under the same conditions. I don’t know what the situation is.
Under V8.4, the T-xy phase diagram does not look like this. I wonder if the poster has set it wrong? The phase diagram I made looks like this:
Try the Wilson method instead.
Yours is obviously an xy detailed drawing, isn't it T-xy? ?
Brother, take a closer look and see why this is not a T-xy phase diagram. . . . The abscissa is the component content, and the ordinate is the temperature. Isn't this a standard T-xy phase diagram? . .
