CHAPTER 15 Vessels
Chapter Overview
In the process industries, vessels are containers used for storage or the additional
processing of products. Vessels vary in design, purpose, and process requirements.
The process technician is responsible for understanding the purpose of each vessel
along with any associated components and is responsible for the safe operation of all
vessels.
