Course Objective

Upon completion of this course, participants will gain a basic understanding of the main components and subsystems of audit procedures. They will learn to critique the advantages, applications, performance, and economics of different plant features and alternative features that audits may indicate need to be retrofitted.

Participants will learn about the influence of various auxiliary systems including instrumentation and controls, process accessories, the process itself, and how this can contribute to an effective audit. They will also learn some basics about the role of operations personnel and training and how they can help maximize audit effectiveness.

Participants will discover the basics required in minimizing operating cost and optimizing efficiency, reliability, and component longevity and will learn about the overall legislative limits the plant must operate within (including monitoring and control of environmental emissions) and any changes in same. They will gain insights into predictive and preventive maintenance, reliability and testing, and what that does for audit planning. Finally, they will discover some of the latest technology in all of the above and identify methods for self-improvement.
