Introduction

This course provides a comprehensive understanding of the operations and processes involved in Crude Distillation Units (CDU), which are the primary units in oil refineries for separating crude oil into various fractions based on their boiling points. Participants will gain an in-depth knowledge of the unit’s design, operational principles, and key factors that influence its performance. The course will cover the entire distillation process, including the chemistry behind the separation of crude oil, equipment used, and the operation of the distillation column, as well as optimization and troubleshooting techniques to improve CDU efficiency.

Objective

By the end of this course, participants will be able to:

Understand the fundamentals of crude oil distillation and its importance in the refining process.
Learn about the components and equipment involved in a Crude Distillation Unit.
Understand the principles of separation and the role of the distillation column in fractionating crude oil.
Explore the operational parameters and conditions that affect the performance of a CDU.
Gain knowledge of the different fractions produced in crude distillation and their uses in the refinery.
Learn troubleshooting and optimization strategies to enhance CDU efficiency.
Understand the impact of crude oil characteristics on CDU operations and performance.
