•Explain the Temperature-X-Y diagram Water, at a temperature of 82 °C, will boil if the pressure is Methanol has a lower boiling point (65 °C) than water. The feed contains 40 mol% methanol where a fraction feed (f) is vaporized, (b) Use the Txy diagram to estimate the minimum and maximum temperatures at.

In addition, the tie lines or isotherms are shown in green. The data obtained in our simulation, for, agrees very well with those given in Henley and Seader’s classic textbook [1], which are shown by red dots.
The vapor-liquid equilibrium data is also plotted in a separate diagram. For example it will take about 75 kJ to change 1 kg of air at 25oC and 1 atm to oC and 1 atm.
It will take much more energy, about kJ, to change 1 kg of water at oC and 1 atm to water vapor (steam) at the same temperature and pressure. Vapor-Liquid Equilibrium Data.
The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition. The data represent a small sub list of all available data in the Dortmund Data Bank.

ý The Txy diagram for water-benzene looks wild because there is a range where there can be more than one liquid phase in equilibrium: In the T range from the boiling point of benzene (approx 80 C) down to about 55 C, lines of constant T cross the blue liquid composition (water mole fraction x) line twice. azeotropic data for binary mixtures Liquid mixtures having an extremum (maximum or minimum) vapor pressure at constant temperature, as a function of composition, are called azeotropic mixtures, or .VLE-Calc – Vapor-liquid equilibrium database, calculations and phase diagram drawingVLE-Calc – Vapor-liquid equilibrium database, calculations and phase diagram drawing
