Distillation is the use of phase transitions to concentrate chemicals from a mixture.

For example, cooling a mixture of [[ethanol]] and [[water]] to below the freezing point of water but above the freezing point of alcohol would turn some of the water into ice. Separating the solid from the liquid, one ends up with one mixture that is higher in water than the original and another that is higher in ethanol.

Similarly, an oil refinery heats crude oil so that some of the contents evaporate while others stay liquid. Doing this in multiple steps, one can separate it into a number of components such as diesel fuel, petroleum/gasoline or [[kerosene]].

Since [[yeast]] can not be used to produce ethanol in concentrations beyond that which kills the yeast, and since ethanol has significant medical use, a self-sufficient colony would likely need to distill it.

+Distillation differs from fractional crystallization, zone melt refining and zone freeze refining.  An example of fractional crystallization is cooling a mixture of [[ethanol]] and [[water]] to below the freezing point of water but above the freezing point of alcohol.  Some of the water turns into ice and is separated.  Melting the ice gives one mixture that is higher in water than the original while the unfrozen liquid is higher in ethanol.
