CHME - UOL - Continuous Distillation

Continuous Distillation

Equipment Specifications

  • 12 sieve trays with a partial reboiler and total condenser.
  • Saturated or subcooled liquid feed can be fed to tray 1, 7, 12, or directly to the reboiler.
  • Column can be operated manually or using the DeltaV™ DCS.
  • Thermocouples and sample ports on each tray allow for temperature and liquid composition data to be collected.
  • Alarms and interlocks are present for process safety.

Possible Experimental Objectives

  • Distillation of binary or tertiary mixture.
  • Measuring of pressure drops across each tray using a single component.
  • Energy balances to determine heat loss.
  • Temperature inferred composition control.
  • Feedforward control for disturbances in feed composition or flow rate.
  • Process modeling for predicting and fitting data incorporating pressure drop, heat loss, tray efficiency, and non-ideal vapor-liquid equilibrium.
