CHME - UOL - Batch Distillation

Equipment Specifications

• 6 sieve trays with a partial reboiler and total condenser.
• Equipment can be operated as a traditional batch rectification column or an inverted batch stripping column.
• Column is operated 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

• Batch stripping or rectification 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.
• Rayleigh analysis to predict and analyze changing compositions.
• Process modeling for predicting and fitting data incorporating pressure drop, heat loss, tray efficiency, and non-ideal vapor-liquid equilibrium.
