1. A center feed system for coking a drum comprising:
- an inlet sleeve attached to a sidewall of a reservoir vessel; and
a retractable injection nozzle contained within the inlet sleeve, the retractable injection nozzle adapted to extend into the reservoir vessel to allow residual byproduct to flow therethrough and into the reservoir vessel, and adapted to retract from the reservoir vessel and into the inlet sleeve, wherein the retractable injection nozzle is shaped such that retracting the retractable injection nozzle into the inlet sleeve blocks the flow of residual byproduct through the retractable injection nozzle, and wherein the retractable injection nozzle includes a fluid obstruction apparatus.

Abstract
A center feed system for use within a delayed coking system, or any other similar system is described. 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 a vessel, thus effectuating or inducing even thermal distribution throughout the vessel.

19. A center feed system for coking a drum comprising:
-
a spool that is configured to attach to a coke drum; an inlet sleeve attached to a sidewall of the spool; and a retractable injection nozzle contained within the inlet sleeve, the retractable injection nozzle adapted to extend into the spool to allow residual byproduct to flow therethrough and into a coke drum to which the spool is attached, and adapted to retract from the spool and into the inlet sleeve, wherein the retractable injection nozzle is shaped such that retracting the retractable injection nozzle into the inlet sleeve blocks the flow of residual byproduct through the retractable injection nozzle, and wherein the retractable injection nozzle includes a fluid obstruction apparatus. - View Dependent Claims (20)
