By adding water or steam the boiling points of the compounds are depressed, allowing them to evaporate at lower temperatures, preferably below the temperatures at which the deterioration of the material becomes appreciable.

Increasing or lowering pressure can also change a boiling point, im just not sure which one lowers it and which one raises it.

the elevation may have changed the boiling point. the higher you go, the lower the boiling point.

Its easy, just use a vacuum distiller or "vacuum pan."
