Vapor Liquid Equilibrium Apparatus

The Present set-up consists of distillation still with a heating element. An electrical Dimmerstat is connected to heating element for varying heat input. The vapours form the top of column are condensed in the shell and tube type condenser by circulating cooling water. The condensate is collected in reflux drum and feedback to column as reflux. A tank with pump is provided to circulate cold water to condenser. Flow rates can be regulated through control valve fitted. Instrumentation is provided to measure the temperatures at different points.
