Case Study: Alkylation Limitations for Gulf Coast Refinery

Alkylation Limitations for Gulf Coast Refiner

The Challenge to the Customer

In the Spring of 2004, a Gulf Coast refiner contacted Aggreko to evaluate cooling limitations within the alkylation unit. High reactor temperatures were limiting production and causing a loss in octane number and an increase in acid consumption. Demand for the alky unit was at an all time high and the client wanted the project completed and on-line as soon as possible

Aggreko's Solution

Aggreko Process Services' engineers remained onsite to complete the Process Design Package while the equipment was being delivered and set-up. The review and operator training were completed prior to start-up of the project.

The project was started up without incident. Within a few hours the reactor temperature had been lowered by 10°F.

The Benefit to the Customer

This project has allowed the refiner to maintain the desired production rates, increased the octane value by one octane number and reduced acid consumption significantly. The comments from the customer confirm the value that Aggreko Process Services brought to the project.

“When Aggreko Process Services got involved with the project, our expectations were exceeded. We were unaware of Aggreko Process Services and the expertise, professionalism, and added value they bring to a project. After our initial meeting, we were completely confident in their abilities and trusted their recommendations. Their commitment to remain onsite to complete the final design work showed their dedication to the project. It was a pleasure working with the Aggreko Process Services team and we look forward to working with them on future projects." - Refinery Plant Manager
