Continuous distillation water alcohol

This unit is design as a pilot scale plant. The column can be fed at several levels through the SS intermediate plates placed along the column.

The flow transmitters, the temperature sensors and the available pressure indicators, allow the user to monitor the processand

to study the influence of the different parameters and the operating conditions.

The DCS and the software application developed for this unit allow parameters variations,process automation and data acquisition in real time and/or historical (extra period).


Study of the transitional phases

Start the unit

Put equilibrium conditions

Stop the unit


Research of the optimum operating parameters

Feed rate, the preheating temperature, rate reflux, the pressure loss of column


Study of the adjustments of the parameter’s control


Multivariable process implementation
