Inside a delayed coker, the transition between foam and coke is more than simply a change in material. Knowing where that transition occurs can be important when managing the coking cycle and protecting the operation from unwanted events such as foam-over.
This is one of the reasons understanding the foam-to-coke interface is an important consideration when selecting coke drum monitoring technology.

Monitoring the changing conditions inside a delayed coke drum is an important part of managing the coking cycle. As material moves through different phases, operators need reliable information at critical points within the drum to help monitor coke formation and identify conditions that could lead to foam-over.
There are several technologies available for coke drum monitoring, including gamma transmission and neutron backscatter. While both use radiation-based measurement, they work in fundamentally different ways and provide different types of information.
So, what is the difference and why does it matter?

Knowing where coke is forming and how the level is progressing inside a delayed coker is an important part of managing the coking cycle.
As the drum fills, the contents change through different phases, including vapour, foam and coke. Operators therefore need measurement technology that can provide reliable information at the points that matter.
But how is coke level actually measured in a delayed coker?
