About the course

Distillation is a critical process in oil refining, separating crude oil into valuable fractions through atmospheric and vacuum distillation. This process involves complex chemical and mechanical systems that must operate efficiently to ensure optimal performance and safety. However, challenges such as corrosion and material degradation can significantly impact system reliability, requiring in-depth knowledge of process operations and failure mechanisms.

In this training course, you will explore the fundamentals of crude oil distillation, gain insight into process flows, and understand the role of corrosion loops in system integrity. You'll also delve into common corrosion mechanisms, including stress corrosion cracking and naphthenic acid corrosion, and learn to recognize and mitigate their effects on refining equipment.

This course consists of 3 online modules based on video content.
