Fractional distillation using a rectification column. P3031640

You can get the concept of:
Rectification columns, rectification, continuous and discontinuous distillation, vapor pressure, evaporation, condensation, gas chromatography.

Principle:
In countercurrent distillation (rectification) using columns rising steam can interact with the condensate. In this case, fractional distillation, namely, step by step distillation for separation of substances with similar boiling point, can be performed in one device. By using distillation column can remove condensate from its individual plates.
