Abstract: The present invention features a coke drum de-heading system comprising (a) at least one coke drum having an orifice therein; (b) a de-header valve removably coupled to the coke drum designed to de-head the coke drum; and (c) an exchange system, including an upper and lower bonnet and other elements and members adapted to integrate the de-heading system, and particularly the de-header valve, into the manufacturing system.

Abstract: A coke drum bottom de-heading system having an internal shroud enclosure and a shroud end cap opened by a flange to a coke bottom de-heading valve capable of accepting the end of a gate valve upon actuation. Acting in coordination with the shroud enclosure to prevent the escape of steam is a gate seal assembly having a gate seal slidably engaged against the sliding gate to prevent the passage of steam thereby.

Abstract: The present invention features a coke drum de-heading system that provides unique advantages over prior art de-heading systems, namely the de-heading of a coke drum without having to physically remove the head units. This is essentially accomplished using a specially designed dual seated, linear motion goggle blind gate valve, or de-header valve, that is removably coupled to and seals against the flanged portion of a coke drum much the same way a conventional head unit would be attached. The de-header valve is equipped with, among other things, a sliding blind that is contained and capable of moving within an upper and a lower seat, wherein one of such seats is a floating dynamic, live loaded seat that is capable of automatic adjustment through one or more loading zones so as to seal the blind between the upper and lower seats.
