  • identify the performances and limits of different control systems,
  • deepen their knowledge of the detection and effects of deficiencies.
Course Content

OPERATING PARAMETERS: DEFINITION & SIGNIFICANCE

0.5 day

  • 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.

FRACTIONATION CAPABILITY OF AN INDUSTRIAL DISTILLATION COLUMN

0.5 day

  • 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.

PROCESS CONTROL PARAMETERS

3 days

  • 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, such as a depropanizer, a debutanizer and 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 control systems based on quality measurement.
  • 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).

EQUIPMENT TECHNOLOGY & TROUBLESHOOTING

1 day

  • Trays: technology, workings; 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.
