Abstract
The present invention relates to a safety system during the entire delayed coker operation. The present invention preferably comprises a coke drum; a first coke drum de-header system coupled to the bottom of the coke drum; a second coke drum de-header system coupled to the top of the coke drum; a containment system coupled to the second coke drum de-header system; and a remote switching system. Hence, the present invention provides system for cutting coke within a coke drum with increased safety, efficiency and convenience.
Claims31
A system for providing a safe working environment during delayed coker operations, said system comprising:
- a coke drum;
- a first coke drum de-header system coupled to the bottom of the coke drum;
- a second coke drum de-header system coupled to the top of the coke drum;
- a containment system coupled to the second coke drum de-header system;
- and
- a remote switching system.
A method for safely removing coke from a coke vessel, comprising the steps of:
- coupling a coke drum to a main body of a deheader valve;
- supporting said valve;
- and
- creating a metal to metal contact seal between said valve closure and said means for supporting a valve closure, said contact seal shearing any accumulated coke upon actuation of said valve closure;
- pressurizing liquid;
- ejecting high pressure fluid from nozzles dedicated to boring on a cutting head to begin boring a hole through said coke, wherein said cutting head is comprised of a plurality of nozzles separated into two groups, one group for boring and one for cutting, each independently supplied by fluid
- ejecting high pressure fluid from nozzles dedicated to cutting coke on a cutting head to begin cutting said coke within said coke vessel;
- wherein said cutting head is comprised of a plurality of nozzles separated into two groups, one group for boring and one for cutting, each independently supplied by fluid;
- containing the de-coking system with a continuous containment system.
