COURSE OVERVIEW:

This course will provide deep technical knowledge and practical experience related to C5 C6 hydroisomerization units. It focuses on the overall refinery context of the isomerization unit, the detailed Process Flow Diagram (PFD), key process variables, gas and liquid drying systems, reactors, and catalyst protection. Participants will understand how the unit is configured, how each major item of equipment contributes to octane improvement, and how operating conditions influence conversion, selectivity, and catalyst life. The course places strong emphasis on recognizing catalyst poisons and contamination sources, interpreting unit data, and applying structured troubleshooting techniques to restore and optimize performance, with special attention to the client’s specific unit configuration.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Explain the significance of the C5 C6 isomerization unit within the overall refinery scheme and gasoline pool.
2. Describe the main chemical reactions involved in C5 C6 isomerization and the role and characteristics of the catalysts used.
3. Read and interpret the Process Flow Diagram (PFD) of the client’s isomerization unit and identify the function of each major item of equipment.
4. Identify and explain the roles of gas and liquid dryers in feed preparation and catalyst protection.
5. Describe the configuration, operation, and monitoring of isomerization reactors and associated recycle systems.
6. Define the key operating conditions and process variables, and explain their impact on unit performance, product quality, and catalyst life.
7. Recognize common catalyst poisons, their sources, and strategies to prevent or mitigate their impact on the unit.
8. Outline and explain the main steps in startup and shutdown of the isomerization unit and associated drying and reactor systems.
9. Apply a structured approach to troubleshooting typical operating problems, including off specification octane, low conversion, high pressure drop, and abnormal temperature profiles.
10. Relate theoretical principles and generic isomerization know how to the particular configuration and design of the client’s unit.

TARGET AUDIENCE:

-Operation engineers working on isomerization and naphtha processing units

-Panel and field operators supporting advanced unit operation and troubleshooting

-Process engineers involved in monitoring, optimization, and support of the isomerization unit

-Refinery technologists and technical staff responsible for gasoline pool quality

-Maintenance and reliability personnel closely involved with dryers, reactors, and associated equipment

-Senior operators and shift supervisors who coordinate unit startups, shutdowns, and upset handling

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures and discussion sessions, as well as case studies, will be managed to maximize the amount and quality of information, knowledge, and experience transfer. The course will be intensive but practical and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance learning. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and after the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
