Abstract
The inlet of a coke chute is pushed upwards by a plurality of actuators until it encompasses the bottom outlet of a coking vessel. The inlet is preferably surrounded by a skirt which tapers inwardly from top to bottom, and the entire chute is preferably retractable below the level of the floor underneath the coking vessel. A plurality of locks can be used to secure the skirt to the lower portion of the vessel.
Claims14
An apparatus for channeling the flow of coke from a bottom outlet of a coking vessel, comprising:
- a coke chute having an upper portion sized and dimensioned to circumferentially encompass the bottom outlet of the vessel;
- and
- a plurality of actuators positioned to push the upper portion of the chute into a proximate relationship with the bottom outlet such that essentially all of the coke flowing through the bottom outlet is channeled through the chute.
An improved delayed coking system having a coking vessel with a bottom outlet and a coke chute with an upper inlet, the improvement comprising:
- the inlet sized larger than the outlet;
- the chute collapsible between an extended position and a retracted position;
- and
- at least one actuator positioned to push up a portion of the chute such that the inlet encompasses the outlet.
A method of directing coke from an outlet of a vessel to a coke pit comprising:
- providing an extensible coke chute having an inlet and a passageway to the coke pit;
- providing at least one actuator coupled to the coke chute;
- actuating the actuator to push the inlet up to and around the outlet;
- and
- allowing the coke to flow through the chute.
