Bubble and dew points at same composition

WebThis liquid mixture is non-ideal, and the system has an azeotrope (a condition where liquid and vapor have the same composition). The blue curve represents the liquid-phase boundary (bubble point), and the green curve represents the vapor-phase boundary (dew point). You can vary the temperature for the diagram. Click and drag the black dot to ... WebThus the bubble point is 126.14°C and the dew point is 130.39°C. Since 400K (126.85°C) is between the bubble point and the dew point, we would expect a mixture of vapor and liquid at that temperature. The program flash was used to find the vapor fraction and the composition of the liquid and vapor by the same procedure shown above. Here are ...
