Abstract: A fluid catalytic cracking unit fractionator comprising a fractionator column having a slurry pumparound section and a bottom liquid section. The slurry pumparound section comprises an upper bed and a lower bed each disposed in the fractionator column. The slurry pumparound section further comprises an upper liquid distributor (such as a spray header comprising a plurality of upper nozzles) disposed above the upper bed and configured to distribute liquid from the bottom liquid section onto the upper bed. The slurry pumparound section also comprises a lower liquid distributor (such as a spray header comprising a plurality of lower nozzles) disposed below the upper bed and above the lower bed and configured to distribute liquid from the bottom liquid section onto the lower bed.

Abstract: The present disclosure generally relates to method and apparatus for preventing coke formation in reactor vapor feed nozzle of a fractionator column of a fluid catalytic cracking unit. One or more baffles are positioned within the fractionator column to prevent effluent vapor that is directed by the reactor vapor feed nozzle into the feed zone from flowing back into the reactor vapor feed nozzle. The reactor vapor feed nozzle itself, or an internal nozzle coupled to the reactor vapor feed nozzle, may extend at least partially into the feed zone to similarly act as a baffle.

Abstract: A hydrocarbon distribution system is provided. The hydrocarbon distribution system has a vessel shell. A vapor distribution tray is disposed within the vessel shell. A first spray header and a second spray header are disposed above the vapor distribution tray. A draw system is disposed above the first and second spray headers. The hydrocarbon distribution system reduces clogging of nozzles, and improves product quality.

Abstract: Embodiments described herein provide a method and apparatus for stabilizing a product, such as a petroleum or other hydrocarbon based product, for example crude oil. Stabilization removes volatile components from the crude such that the crude product may be safely handled, stored, and/or transported. In one embodiment, the crude stabilization system includes at least a stabilizer column and an overhead system. Effluent from the stabilizer column may be fed directly into a suction inlet of a compressor system of the overhead system. The stabilizer column is preferably operated at low pressures and temperatures, thus making a desalting system unnecessary. Furthermore, overhead trim cooling, recycle cooling, and interstage cooling may be provided by the crude feed rather than air coolers or cooling water. As such, stabilized crude product may be safely transported via any means of transportation, such as a railcar.
