Distillation Certification

5 days PSE/DSS-E
Level
Advanced
Audience
  • Engineers, process engineers, process control personnel and technical staff in the refining and petrochemicals industries.
Purpose
  • To provide a comprehensive understanding of efficient distillation columns operations.
  • To implement optimization strategies.
Learning Objectives
  • To learn about all parameters and profiles for the analysis of a distillation column operation.
  • To master the concepts necessary to optimize the operation of a column.
  • To identify the performances and limits of different control systems.
  • To deepen knowledge of the detection and effects of deficiencies.
Ways and means
  • Highly efficient learning process : operation of a virtual column using a dynamic simulatorthat models the main physical phenomena of distillation.
  • Troubleshooting case studies to illustrate process control schemes.

OPERATING PARAMETERS: DEFINITION AND 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 AND 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.
