Fractional distillation through the plate column

In the distillation process in counter-current through the distillation column, the vapour that rises enters into interaction with the condensate. In this way, a fractional distillation or a distillation at stages for the separation of substances with close boiling points can be obtained in a single apparatus. If you are using a column with bell-like plates, the condensate can be removed from the individual plates. The products of the head, bottom and in the middle column can be examined and compared by means of gas chromatography
