Course 8107      CEUs: 2.8

This course is for technicians, engineers or other persons who have responsibility for troubleshooting paper machine processes, minimizing process variability and improving product uniformity.

Overview  

This is a 4-day course that captures the experience that EnTech has developed over years of auditing paper machine and stock supply systems. The course looks into a broad scope of process variability and operational stability issues that affect process reliability and performance. Issues that are examined are related to process design problems, instrumentation capability, control strategy design, loop tuning deficiencies, and advanced control. A series of simulators have been designed to allow participants to discover the problems and their solutions while providing positive feedback on the results obtained.

Prerequisites

Participants should have taken Applied Modern Loop Tuning Process (9032) or Control for Engineers I (9030) or possess similar process control and instrumentation knowledge related to paper machine applications.
