A deheader valve is fitted onto an existing or new coke drum by initially positioning the body and valve, and then raising the valve to mate with the flange using a lifting device other than a chain fall. The vertical positioning of the deheader valve is preferably accomplished with a hydraulic or pneumatic piston, winch, scissor jack, ratchet jack, screw jack, and so forth. The distance traveled by the valve using these devices is more than 2 cm, commonly at least 20 cm, and in some installations up to 40 cm or more. In retrofit situations an oil inlet is provided in a side wall of the drum above the bottom drum flange.

Valve installation apparatus and methods

Improved coke chute systems () include a lock () that receives and automatically secures a coke-receiving conduit () to a coke vessel after the lock () is switched to a closed position. Contemplated systems may further be combined with a horizontally movable coke chute cover, or a cover that is moved by an actuator () that lifts and rotates the cover from a first position to a second position.

Coke chute systems and methods therefor

An apparatus comprises a movable lock ring and a lock arm that prevents inadvertent movement of the lock ring. Contemplated configurations are especially useful in delayed coking vessels to prevent opening of the vessel while the vessel is in operation.

Safety lock boltless closures

A high-pressure device has a drill stem () with a drill head () delivering a high-pressure fluid jet. A shield () is movably coupled to the device, wherein the drill head () is at least partially enclosed by the shield () when the drill head () is removed from the container ().
