1.5KW Vacuum Distillation Machine GG-17 High Borosilicate Glass
|
Fractional distillation column is a fractionating column used for the separation of miscible liquids. It is a long glass tube with wide bore. It either filled with glass beads, small stones, porcelain rings or coke. It can also be blown in to a shape with several spheres or pear bulbs. The purpose of the glass beads is that they improve the distillation process.
There can be several trays in the fractionating column in place of glass beads and bulbs. These trays are called theoretical plates. Theses trays or theoretical plates serve the purpose of the glass beads.
For commercial purpose fractionating column with hundredth of theoretical plates are used. The main aim of using the fractionating column is to increase the surface area for cooling of liquid and to provide hurdles to the rising vapours and descending liquid.
