COKE DRUM BOTTOM DE-HEADING SYSTEM

WIPO Patent Application WO/2004/104505

A2

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. The de-header valve itself comprises (1) a main body having an orifice dimensioned to align with and couple to, in a concentric relationship, the orifice of the coke drum; (2) a live loaded seat assembly coupled to the main body and comprising a dynamic, live loaded seat, a live seat adjustment mechanism coupled to the main body and designed to control and adjust the force and resulting seat load of the dynamic, live loaded seat, and a force transfer module in juxtaposition to the dynamic, live loaded seat for transferring the force from the live loaded seat adjustment mechanism to the dynamic, live loaded seat; (3) a static seat positioned opposite from and counteracting or counterbalancing the dynamic, live loaded seat; and (4) a blind or sliding blind capable moving in a linear, bi-directional manner within the de-header valve and between the dynamic, live loaded seat and the static seat, such that upon actuation of the blind from a closed position to an open position, the coke drum is de-headed.
