Fractional distillation with the bubble tray column with Cobra4

Posted on

Item no.: P3031660 Principle In countercurrent distillation (rectification) using a column, the rising vapour can enter into interactions with the condensate. In this manner, a fractional distillation, i.e. a distillation in several steps for the separation of substances with similar boiling points, can be performed in a single apparatus. If bubble tray columns are used

Rectification – the number of theoretical trays in a distillation column

Posted on

Item no.: P3031501 Principle The separation power of a rectification (fractionating) column can be determined using an appropriate binary mixture whose equilibrium composition is measured in the distillation flask and in the domed glass head of the distillation apparatus. The number of theoretical trays can be numerically or graphically obtained from the measured values. Tasks
