Vapour- Liquid Equilibrium Set-up.
Vapour- Liquid Equilibrium Set-up
The basic data of any distillation problem are the equilibrium
between the liquid and vapour phases of the system subjected to
distillation. Hence is of great importance to study the vapour-liquid
equilibrium. The 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.
