PIGNAT Controlled Distillation Unit – OTP-DC



OTP pilots allow work on industrial scale in various fields: chemical engineering, maintenance, supervision.

  • Understand the continuous distillation process
  • 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.
  • This unit is designed 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 process and 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).
