Исходная смесь (жидкость), состоящая из двух компонентов, поступает в колонну. Ректификационная колонна имеет цилиндрический корпус, внутри которого установлены контактные устройства в виде тарелок. Из ребойлера (кипятильника) в нижнюю часть колонны поступают пары, которые движутся вверх. Это восходящий поток. Пары проходят через слой жидкости на тарелках. Компонент смеси, имеющий меньшую точку кипения, в виде пара поступает в верхнюю часть колонны, а затем в конденсатор, где конденсируется. Полученная жидкость, проходя через сборник орошающей фракции, подается на верхнюю тарелку колонны. Это нисходящий поток. Жидкость, выходящая из низа колонны делится на две части. Одна часть направляется в кипятильник, другая – в сборник.

Fractionation towers use various liquid contacting methods to provide the required number of equilibrium stages. Such devices are commonly known as “plates” or “trays”. Each of these plates or trays is at different temperature and pressure. The stage at the tower bottom has the highest pressure and temperature. Progressing upwards in the tower, the pressure and temperature decreases for each succeeding stage.
Another way of improving the separation in a distillation column is to use packing material instead of trays. These offer the advantage of a lower pressure drop across the column.

The column can be fed in different ways. If the feed is from a source at a pressure higher than the fractionation column pressure, it is simply piped into the column. Otherwise, the feed is pumped or compressed into the column. The feed may be a superheated vapor, a saturated vapor, a partially vaporized liquid-vapor mixture, a saturated liquid or a sub-cooled liquid. If the feed is a liquid at a much higher pressure than the column pressure and flows through a pressure let-down valve just ahead of the column, it will immediately expand and undergo a partial flash vaporization resulting in a liquid-vapor mixture as it enters the fractionation column.
