Abstract
A system that reduces worker exposure during coke drum unheading and cutting operations and that reduces risk to workers also provides a capacity increase in that the time a coke drum is not being filled is reduced. This system employs a containment shield that safely permits drainage through the bottom head and contains water and coke avalanches.
