 As world demand for petroleum coke, a byproduct of petroleum refining, continues to increase, refiners need cost-effective and reliable solutions for their coking needs. For years, coke drum bulging and cracking has been a maintenance and reliability problem for refiners, resulting in costly and time-consuming shutdowns. CB&I’s patented Vertical Plate Coke Drum™ is a cost-effective, long-lasting solution to a decades-old problem.
The plates on our coke drum are oriented vertically, providing up to 50 feet of shell length without a girth seam.
The result is a reliable vessel that can endure the most severe thermal cycles, thus outlasting traditional drums and reducing maintenance costs.
A New Solution to an Old Problem. Severe thermal cycling over the life of a traditional coke drum weakens the base material near the circumferential seams, causing bulging and cracking. But our drum’s innovative design eliminates circumferential weld seams in the vessel’s midsection and lower portion, where damage is most likely to occur.
As a true EPC company, we have the in-house expertise to accomplish the project from start to finish. We provide design and detail engineering services, and fabricate the vessel at our own facilities. Our people also mobilize the crane and erect the vessel at the project site.
Installation Options. We can install the Vertical Plate Coke Drum as new construction or retrofit an existing vessel. Replacement drums can be installed in any of three ways:
Complete can section replacement–A large-capacity crane is used to remove the entire can section and install one or two vertical plate replacement sections.
Plate-by-plate replacement–When there is insufficient area for a large-capacity crane, the damaged drum plates can be cut and removed one by one, then replaced with vertical plates.
Full drum replacement–The derrick structure above the drum is lifted; the entire damaged drum is removed intact; and the Vertical Plate Coke Drum™ is set in place.
We have installed our Vertical Plate Coke Drum at several refineries at a cost that was lower than or comparable to traditional drum installations. When the increased reliability and longer life of our drum is factored in, our customers can expect to see reduced maintenance and ownership costs over the life of the vessel.
