T-xy Diagrams
To make this diagram, it is needed the pressure in which it is. We substitute the pressure in Raoult's equation to calculate the saturation temperature.
P-XY DIAGRAMS
With the temperature we obtain the parcial pressure of each component, and with those we can obtain the total pressure. This is calculated by adding the partial pressure of each component times its composition.
Now we are going to show you a T-xy Diagram of Benzene and Toluene. It was made using Excell
Now that the topic is clearer we are going to use it with a mixture of water and ethane using ASPEN software:
