The set-up is designed to demonstrate and stimulate the phenomena of crystallization. Swenson Walker crystallizer is a continuous type crystallizer. This operation involves both heat and mass transfer. Crystallization is the formation of solid particles within a homogeneous phase. Its wide use has a two-fold basis; a crystal formed from an impure solution is itself pure.

The setup consists of a top open jacketed round bottom trough. A ribbon mixer is provided in crystallizer trough, which rotates at low rpm for agitation of saturated solution. The saturated solution is prepared in a tank fitted with heater and a stirrer. This hot saturated solution is fed at one end of the crystallizer and flows slowly towards the other end while being cooled and is allowed to flow back in hot feed tank making the process continuous. The crystals sediments at the bottom of the trough, and can be washed out at the end of process. Arrangement for Cooling water circulation and flow measurement in jacket is made by using storage type water tank, a pump and a rotameter. Necessary instrumentation is done for temp measurement

The set-up is designed to demonstrate and study the vapor-liquid equilibrium. As basic data of any distillation problem is the equilibrium between the liquid and vapor phases of the system subjected to distillation. Hence it is of great importance to study the VLE.
The set-up consists of distillation still with a heating element, shell & tube condenser, reflux & distillate section. A tank with pump is provided to circulate cold water to condenser. Flow rates can be regulated through control valve fitted. Instrumentation is done to measure the temperatures at different points.

A Digital Temp. Controller is connected to heating element for precisely controlling & varying heat input. The vapors 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

The set-up is designed to demonstrate and study of heat & mass transfer during the process in a forced draft counter flow type water cooling tower.
The set up consists of specially designed; SS vertical tower packed with aluminium mesh packing, fitted with front side acrylic window to provide actual visualization of cooling tower operation.
The air from a blower enters at lower end of tower and after passing through the mesh packing leave the column from top outlet to atmosphere. Counter – currently hot water from water bath is evenly distributed over the packing by nozzles at top of the tower using circulation pump.

An arrangement is made to vary and measure the airflow rate & temperatures at different locations in the tower. The hot water bath is provided with level gauge enables to show the exact evaporation loss. The temperature of water in bath can be independently varied to simulate different conditions using digital temp
