Paper machine dryer control optimization

---

  The dryer section plays an important role in paper machine operating efficiency, energy consumption and product quality. Accordingly, dryer section optimization is a high priority. In the area of dryer section control there is much room for improvement. Valve flaws, lack of instrumentation for diagnostics, and poor tuning all degrade regulatory loop performance. There are often no supervisory strategies in place to manage the drying load, respond to sheet breaks, optimize energy efficiency and deal with the fundamental non-linearities in the dryer loops. These supervisory strategies can be easily implemented in modern distributed control systems. 

  The objective of this course is to provide the attendees with the knowledge and tools to improve dryer control performance. Paper Machine Dryer Control Optimization is a hands-on course that uses a process simulation as a learning tool to understand dryer process fundamentals, dryer controller tuning, regulatory and supervisory control strategy options, and troubleshooting techniques. 

  The course is primarily intended for process engineers, control engineers or instrumentation engineers who have responsibility over the optimization of the paper machine dryer section. The course explores the implications of process equipment design and process variability and therefore would be beneficial for maintenance and design engineers.
