For 10 points, name this process that consists of boiling a liquid and condensing its vapor.
In the bulb-to-bulb form of this process, an apparatus known as a kugelrohr is used. Before performing one type of this process, a McCabe–Thiele diagram may be drawn. The minimum number of equilibrium stages needed for another type of this process can be determined with the Fenske equation. Pieces of glass tubing known as Raschig rings are used in a Hempel column in a type of this process, which also may utilize a Vigreux column. Entrainers are added in order to separate azeotropes in this process, and gasoline is separated from petroleum using its "fractional" type. For 10 points, name this process that consists of boiling a liquid and condensing its vapor.
