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.
