Corrosion Control in Refineries and Risk-Based Integrity Management
Consultant/Trainer: Henk Helle
The Petrogenium course on Corrosion Control and Risk-based Integrity Management provides knowledge and background of the corrosion threats that may exist in refineries and it gives guidelines how to design, quantify and organize the response to those threats. The course will deal with all the main refinery processes: crude & vacuum, hydroprocessing, FCCU, amine, SWS and Claus units as well as the role of feedstock in these units.
Participants
Corrosion control and integrity management touches the responsibilities of pretty much all intermediate and experienced refinery personnel, but primarily those in technology and integrity management which includes unit technologists, process, corrosion and mechanical engineers, inspectors and compliance officers. And anyone who is confronted from time-to-time with integrity issues or constraints and wants to gain a clearer perspective may fruitfully follow the course.
This Petrogenium course can be tailored for awareness/inexperienced staff, for intermediate and for experienced personnel. Furthermore the course can be customized for a specific refinery, plant or unit. Naturally the alternative of an in-house course is possible. The option for post-course consultancy/help-desk support is also available.

Learning Objectives
Integrity management in refineries rests on four pillars: one, the origin and nature of corrodents in refinery processes; two, the severity, location and nature of the corrosion processes that these corrodents may cause and sustain; three, the ways to mitigate, detect or prevent corrosion; and finally, how to structure this integrity management process in a refinery organization.
The participants will learn about these four pillars and can compare it with their own knowledge and way of working. Ample time is available for queries and discussion.
