HM 210 BATCH DISTILLATION UNIT
GENERAL DESCRIPTION

This equipment demonstrates a process for separation of a mixture (one soluble in another) of two liquids of different boiling points.

The unit consists of boiler, two distillation columns, condenser, reflux tank, top product tank, vacuum pump, measuring instruments, and other accessories.

The liquid mixture is added to the boiler where the mixed vapor with higher concentration of the lower boiling point component rises in the distillation column. The vapor leaves the top and is condensed in the condenser and the reflux tank. Part of the condensate in the reflux tank is fed back to the top of the column where heat exchange is taken place with the rising vapor. This results in vapor phase being richer in lower boiling point component, and the liquid phase being richer in higher boiling point component. The liquid phase moves down to the boiler. Thus, the mixture in the boiler is richer in the higher boiling point component with time.

Two columns, sieve plate column and packed column with Rasching rings, can be interchanged simply by valve control. Lagging is provided for reboiler, sieve plate column, and condenser.

The unit is installed on a stainless steel frame.

Instruction manual is also included.

TYPICAL EXPERIMENTS
  • Comparison of plate column and packed column performance.
  • Pressure drop across column vs boil up rate.
  • Column efficiency vs boil up rate at total reflux.
  • Top product composition vs time at constant reflux ratio.
  • Manual control of reflux ratio.
  • Plate to plate temperature profiles.
  • Mass balance across the system.
