DESCRIPTION :Rotary dryer is a unit in which drying is done by forced draft action created by hot air. The set-up consists of a long revolving cylindrical shell slightly inclined towards the outlet. The shell is fitted with two brackets for support. Air from a blower passes through a heating chamber serves the purpose of drying agent. An arrangement for rotating the dryer shell at low RPM is provided by means of an electrical motor and a reduction gearbox.Wet feed enters from one end of the cylinder and dry material discharges from the other end. As the shell rotates internal flights lift the solids and shower them down through the interior of the shell. This action increases the contact of wet solid against hot air making the dryer very effective. The flow of hot air is counter-current to solids. Flow control and by-pass valve are fitted to regulate the airflow.

The setup is designed to demonstrate principles of distillation in a Packed Column.

The column is made of Stainless Steel material packed with Borosilicate Glass rasching rings. An electrically heated re-boiler is installed at the bottom of the column. The bottom product is collected in the tank. The vapors form 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 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 is done for pressure & temp measurement wherever is necessary

Vapour Liquid Equilibrium Set Up

REQUEST CALLBACK

Ask for Price

Tthe vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the gas phase and a liquid phase.

The concentration of a vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be a partial pressure (a part of the total gas pressure) if any other gas(es) are present with the vapor. The equilibrium vapor pressure of a liquid is in general strongly dependent on temperature. At vapor–liquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature.

For each component in a binary mixture, one could make a vapor–liquid equilibrium diagram. Such a diagram would graph liquid mole fraction on a horizontal axis and vapor mole fraction on a vertical axis. In such VLE diagrams, liquid mole fractions for components 1 and 2 can be represented as x1 and x2 respectively, and vapor mole fractions of the corresponding components are commonly represented as y1 and y2.[2] Similarly for binary mixtures in these VLE diagrams:

x1 + x2 = 1 and y1 + y2 = 1

Such VLE diagrams are square with a diagonal line running from the (x1 = 0, y1 = 0) corner to the (x1 = 1, y1 = 1) corner for reference.

These types of VLE diagrams are used in the McCabe–Thiele method to determine the number of equilibrium stages (or theoretical plates) needed to distill a given composition binary feed mixture into one distillate fraction and one bottoms fraction. Corrections can also be made to take into account the incomplete efficiency of each tray in a distillation column when compared to a theoretical plate.
