Abstract: A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.

Abstract: A center feed system allows residual byproduct to be injected into a vessel from within the center of the vessel. The center feed system can include an inlet sleeve that is attached to the vessel and a retractable injection nozzle that extends into the vessel to inject residual byproduct into the vessel and that retracts into the inlet sleeve after injecting the residual byproduct. A retractable injection nozzle may include one or more openings that each includes an insert that can be removed from the opening. The inserts can therefore be replaced to customize the functionality of the nozzle or to replace the inserts when they have become worn.
Abstract translation: 中心进料系统允许残留副产物从容器的中心内注入容器。 中心进料系统可以包括连接到容器的入口套筒和延伸到容器中以将残余副产品注入容器中并且在注入残余副产物之后缩回到入口套筒中的可伸缩注射喷嘴。 可伸缩注射喷嘴可以包括一个或多个开口，每个开口包括可以从开口移除的插入件。 因此，可以更换插入件来定制喷嘴的功能，或者当刀片磨损时更换刀片。
