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.

About the Course...

The objective of this course is 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 ProNamics dryer optimization simulator provides a realistic environment to train paper machine operators, E&I mechanics and process engineers. The simulation includes advanced supervisory strategies to improve drying stability, prevent flooding, improve energy efficiency, minimize loop interaction and linearize the control loops. Typical dryer section problems, embedded in the simulator provide an ideal environment to develop troubleshooting skills.

Who Should Attend...
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.
