Distillation Certification - Optimization & Troubleshooting

Practical Simulator Training (CORYS IndissPlus simulator)


Who should attend?

  • This course provides a comprehensive understanding of efficient distillation columns operation as well as optimization strategies implementation.
Audience :
  • Engineers, process engineers, process control personnel and technical staff in the refining and petrochemicals industries.

Level : Advanced

Course Content


      • Material balance of the virtual column: cut point, separation quality and concept of fractionation capability.
      • Column pressure: pressure control and pressure profile along the column.
      • Heat balance. Reflux and reboiling ratio and selectivity assessment.
      • Internal flow rates profiles, concentration and temperature profiles. Concentration peaks.

      • Impact of the parameters related to the fractionation capability:
      • Liquid-vapor internal flow rates, associated with reflux and reboiling ratios.
      • Number of theoretical stages and internal equipment efficiency.
      • Position of feedstock inlet related to feed characteristics.
      • Fractionation capability and related energy consumption.
      • Each item is illustrated by practical exercises conducted by trainees on a dynamic simulator.

      • The simulator handling scenario covers the different aspects of operation and control of columns. It starts with a simple control system and implements increasingly sophisticated control systems on increasingly complex columns: from binary to a multiple draw-off column (crude oil distillation).
      • Survey of operating disturbances; origins and causes.
      • Process control strategy and optimization targets.
      • External or internal reflux control, reboiling control with flow rates or duty monitoring.
      • Material balance control: sensitive tray, temperature control systems.
      • Optimization of the heat balance: additional energy through the feed or the reboiler, low pressure operation and energy savings.
      • Implementation of more complex control systems.
      • Analysis of disturbances caused by the feed and systems for feed forward control.
      • Implementation of process control in multi-column trains.
      • Specific case of multiple draw-off columns:
      • Quality tuning through material balance (temperature, flow rate or level control).
      • Heat balance monitoring (role of pumparounds and vaporizing refluxes, optimization of the fractionation capability).
      • The participants can provide diagrams of their distillation columns, the methodology will be applied to confirm that a change of operating parameter does not have the same consequence according to the control scheme implemented.

      • Trays: technology; high efficiency trays, performance and flexibility.
      • Packings and distribution systems: flooding, fouling, mechanical damage and remedies.
      • Reboilers and condensers: implementation and working principles, various control strategies, problems and related origins, possible solutions.
      • The items in this chapter are exemplified by case studies corresponding to actual industrial problems and related solutions.
