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. 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.

14. A coke drum bottom de-heading system comprising:
-
at least one coke drum containing manufactured coke therein, said at least one coke drum having a flanged bottom orifice;
a de-header valve removably coupled to said coke drum to facilitate the removal of said coke from said at least one coke drum by de-heading said at least one coke drum, said de-header valve comprising;
a main body having an flanged orifice therein for removably coupling said de-header valve to said flanged bottom orifice of said coke drum;
an upper and lower bonnet coupled to said main body;
a first seat coupled to said main body;
a second seat coupled to said main body in opposition to said first seat; and
a blind coupled to said main body and actuated by an actuator, said blind capable of moving in a bi-directional manner within said de-header valve between said first seat and said second seat to control the opening and closing of said de-header valve, said blind providing a seal between said first loaded seat and said second seat;
said coke drum is de-headed, thus preparing said coke drum for the removal of said coke, by actuating said blind from a closed, sealed position, to an open position thereby causing said coke that has accumulated on said blind and within said valve to be sheared from said blind. - View Dependent Claims (15)

16. A coke drum top de-heading system comprising:
-
means for monitoring and controlling pressure existing within said de-heading system;
at least one coke drum containing manufactured coke therein, said at least one coke drum having a flanged top orifice;
a de-header valve removably coupled to said coke drum to facilitate the removal of said coke from said at least one coke drum by de-heading said at least one coke drum, said de-header valve comprising;
a main body having a flanged orifice therein for removably coupling said de-header valve to said flanged top orifice of said coke drum;
an upper and lower bonnet coupled to said main body;
a first seat coupled to said main body;
a second seat coupled to said main body in opposition to said first seat; and
a blind coupled to said main body and actuated by an actuator, said blind capable of moving in a bi-directional manner within said de-header valve between said first seat and second seat to control the opening and closing of said de-header valve, said blind providing a seal between said first seat and said second seat;
said coke drum is de-headed, thus preparing said coke drum for the removal of said coke, by actuating said blind from a closed, sealed position, to an open position thereby causing said coke that has accumulated on said blind and within said valve to be sheared from said blind. - View Dependent Claims (17)

18. A coke drum de-heading system comprising:
-
at least one coke drum containing manufactured coke therein, said at least one coke drum having a top orifice and a bottom orifice;
a de-header valve removably coupled to said coke drum and designed to facilitate the removal of said coke from said at least one coke drum by de-heading said coke drum and allowing said coke to pass therethrough, said de-header valve comprising;
a main body having an orifice dimensioned to align, in a concentric relationship, with either of said top and bottom orifices of said coke drum when said de-header valve is coupled thereto;
a seat assembly coupled to said main body and comprising a first seat;
a second seat positioned opposite from and counteracting said first seat; and
a blind capable moving in a bi-directional manner within said de-header valve and between said first seat and said second seat, said blind physically controlled by an actuator; and
such that a seal is created between said first seat, said blind, and said second seat;
wherein said de-header valve de-heads said coke drum and facilitates the removal of said coke from said coke drum upon actuation of said blind from a closed to an open position wherein said coke is sheared. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for de-heading a coke drum following the manufacture of coke therein, said method comprising the steps of:
-
obtaining at least one coke drum designed for the manufacture of said coke;
equipping said coke drum with a de-header valve, said de-header valve removably coupled to said coke drum and comprising;
a main body having means for connecting said de-header valve to said coke drum;
a first seat coupled to said main body;
a second seat coupled to said main body in opposition to said first seat; and
a blind coupled to said main body and actuated by an actuator, said blind capable of moving in a substantially lateral bi-directional manner within said de-header valve between said first and second seats to control the opening and closing of said de-header valve, said blind providing a seal between said first seat and said second seat;
closing said blind and sealing said dynamic, live loaded seat against said blind so as to seal said de-header valve;
manufacturing said coke from a refinery process; and
de-heading said coke drum by actuating said blind and causing said blind to slide across said dynamic, live loaded seat and said static seat into an open position, said dynamic, live loaded seat and said static seat thus shearing said coke in said coke drum as said blind is displaced. - View Dependent Claims (34, 35)

36. A coke drum de-heading valve attachable to a coke drum, said coke drum de-heading valve comprising:
-
a main body having an orifice dimensioned to fit and align with an orifice on a coke drum;
a live loaded seat assembly comprising a first seat;
a second seat aligned with and positioned opposite said first seat;
a blind controlled by an actuator and slidably contained between said first seat and said second seat, such that a seal is created between said blind and said seats, said blind capable of moving in a substantially lateral bi-directional manner between an open, partially open, and closed position, said blind shearing said coke when said blind is caked with coke as said blind is opened, thus de-heading said coke drum. - View Dependent Claims (37)
