Bubble Cap Distillation Column

The column is made of Stainless Steel with seven plates for mounting the bubble caps. Each plate is provided with one bubble cap. An electrically heated reboiler is installed at the bottom of the column. The bottom product is collected in the tank. The vapours form the top of column are condensed in the shell and tube type condenser by cooling water supplied by laboratory overhead tank. The condensate is divided into reflux and distillate by automatic reflux divider and R/D Ratio can be varied. Reflux is fed back to the column and distillate is received in a receiving tank. The complete column is insulated for minimizing the heat loss. Instrumentation provided for pressure & temperature measurement wherever necessary.

Learning Objectives/Experiments:

• To estimate the batch distillation curves for a binary system and verify the binary batch distillation equation for a known number of theoretical plates.
• To operate the column under total reflux condition and estimate the minimum number of theoretical plates required.
