ABSTRACT:
The present invention features systems and methods for de-heading a coke drum without having to physically remove the head units. This is accomplished using a de-header valves that may be removably coupled to a coke drum. The de-header valve is equipped with, a valve closure and a seat support system capable of forming a continuous contact seal during the coke manufacturing process. Actuation of the valve closure functions to open and close the de-header valve. Once the drum is full, the de-header valve may be actuated (opened), wherein the coke that has accumulated on the blind is sheared by the seat support system, thus effectively de-heading the coke drum and facilitating the decoking process.
