Description
Operate a continuous distillation process
The distillation process separates several volatile liquids, simple or complex mixtures, by a series of vaporization and condensation steps. A number of liquids may be separated in this way if their boiling points are sufficiently different. Continuous distillation separates a mixture into fractions: a volatile fraction, the distillate extracted at the column head and a heavy fraction, the residue extracted at the bottom of the column.
Objectives:
- Hydrodynamic study of the column to determine overflooding conditions and/or determine packing factor
- Operate a continuous process to determine materials balance, thermal balance, yield, productivity.
Parameters:
- Feed rate, preheating temperature, reflux ratio, and column pressure drop can be manipulated
- The unit can work in batch or in continuous and with a vaccuum
Proposed Experiments:
- Technical data:
- Column hydrodynamics with water
- Rectification of a binary water-ethanol mixure
- Operations in continuous mode:
- Study of a packed column
- Determine the efficiency of the column by the McCabe-Thiele method (number of theoretical plates).
