Distillation Designer is a small and free Mac software application that offers the simple McCabe-Thiele method for designing binary distillation systems.

Distillation Designer supports:
· Boiling Point Graph showing Vapour-Liquid Compositions.
· q-Line calculation from component thermodynamic properties.
· Manually defining the minimum reflux ratio.
· Loading of Data files.
· Plot of Reflux versus stages to help determine the optimal value.

NOTE: Distillation Designer can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
