Center feed system
First Claim
1. A center feed system comprising:
- a coking reservoir vessel having an opening; and
a retractable injection nozzle comprising an inlet and outlet wherein the retractable injection nozzle is structured to extend through the opening into said coking reservoir vessel while introducing residual byproduct into said reservoir vessel during a coking cycle, and structured to retract out of the reservoir vessel and cover the opening for at least a portion of each coking cycle.

Abstract
The present invention features a center feed system in combination with a coking vessel of a delayed coking system, or any other similar system. The center feed system features an inlet sleeve which slidably engages a retractable nozzle, with inlet and outlet, in fluid connection with a feed source of residual byproduct, allowing residual byproduct to flow from the feed source into the interior of the vessel, thus effectuating or inducing even thermal distribution throughout the vessel. The retractable nozzle is structured to extend through an opening in the coking vessel while introducing the residual byproduct into the coking vessel and retract out of the coking vessel and cover the opening for at least a portion of a coking cycle.

17. A center feed injection system for use within a delayed coking system, said center feed injection system comprising:
-
a spool fittable to a coke drum and a de-header valve such that the spool and the coke drum comprise a reservoir vessel, the spool having an opening; and a center feed system coupled to said spool, said center feed system comprising; a retractable injection nozzle configured to extend through the opening into the reservoir vessel to inject residual byproduct into the reservoir vessel and to retract from the reservoir vessel to seal the opening while the residual byproduct is processed to form coke; an inlet sleeve attached to the spool in slidable engagement with said retractable injection nozzle.

18. A delayed coking system comprising:
-
a feed source capable of delivering a petroleum byproduct to a reservoir vessel; the reservoir vessel; a de-header valve attached to the reservoir vessel; a center feed injection system in operation with said reservoir vessel, said center feed injection system comprising; a retractable injection nozzle comprising an inlet and outlet wherein the retractable injection nozzle is structured to extend through an opening in a sidewall of the reservoir vessel and into the reservoir vessel to inject residual byproduct into the reservoir vessel during a coking cycle, and structured to retract out of the reservoir vessel and cover the opening for at least a portion of a delayed coking cycle.
