Single-Stage Batch Distillation

In this simulation, one mole of a binary mixture undergoes a batch distillation. The first slider sets the mole fraction of the starting liquid. When you click the “click to collect” button, liquid evaporates and the distillate is collected in a collection flask. The amount collected into each flask is set with the second slider. The collection flask is then set aside and an empty flask is substituted. The process repeats when you click the “click to collect button” again, until finally 0.2 mol remains in the still. The equilibrium temperature is shown next to the thermometer. Select either the collection flasks, an x-y plot, or a T-x-y plot to be displayed on the right. Click “reset” to display one of the plots or to start over. You can choose either an ideal solution (no azeotrope), a minimum-boiling temperature azeotrope or a maximum-temperature azeotrope with the drop-down menu. Hovering the mouse over an object reveals further information about that object.
