Description

The setup is designed to demonstrate principles of distillation in a Bubble Cap arrangement. A bubble cap tray has riser or chimney fitted over each hole, and a cap that covers the riser. The cap is mounted so that there is a space between riser and cap to allow the passage of vapor.  Vapor rises through the chimney and is directed downward by the cap, finally discharging through slots in the cap, and finally bubbling through the liquid on the tray. The distillation column is made of Stainless-Steel material with seven trays. An electrically heated re-boiler is installed at the bottom of the column. The vapors from the top of column are condensed in the shell and tube type condenser by circulating cooling water and it is supplied by laboratory overhead tank. The condensate is divided into reflux & distillate 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 is done for pressure & temp. Measurement wherever is necessary.
