Refinery Coke Drum Replacement

Results

Coke Drums absorb a lot of stress. During 24 hours, they fluctuate between ambient temperature and 800°F, causing significant expansion. This stretching, however, is not consistent around the drum’s circumference.

The coke drum can expand inches in one place and not at all in another, which puts substantial stress on the drums and the insulation installed on them. Traditional insulation systems do not accommodate this irregular expansion well.

The engineer for this coke drum project, Fluor, chose a system design that provides insulation with a much longer life than traditional installations.

Fluor designed a cage insulation support system that covers the entire sidewall of the Coke Drum. This system is 6” off the sidewall of the Coke Drum. The cage allows the insulation attached to it to float away from the drum itself. An insulation panel system was installed on the added cage.

Our team designed a system for the top head of the Coke Drum that allows for expansion while in-service. I&I Soft Craft Solutions was awarded this project due to our prior fabrication experience and our ability to offer the best value to the client. We also manufacture standing seam panel systems in several of our fabrication facilities.
