Abstract: In an FCC apparatus and process gas and catalyst exit from a riser, are disengaged from each other and the catalyst is stripped. Product gases are evacuated from catalyst that can over crack the product gases to other undesired products. A baffle in or above the stripping section can direct product gases into a passage that evacuates the product gases to product recovery in isolation from the catalyst.

Abstract: A dehydrogenation process and apparatus contact a paraffinic stream with dehydrogenation catalyst to product olefinic product gases. The olefinic product gases are separated from spent dehydrogenation catalyst and contained in a confined space that has a smaller volume than the reactor particularly at the same elevation. The containment of the olefinic product gases facilitates quenching the olefinic product gases to terminate reaction and improve selectivity to propylene.

Abstract: A plastic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The plastic feed is pyrolyzed at a low-temperature pyrolysis process and subsequently pyrolyzed in a high-temperature pyrolysis process directly to monomers, such as ethylene and propylene. Insufficiently pyrolyzed product from the low-temperature pyrolysis process can be fed to the high-temperature pyrolysis process while preserving the desired low-temperature product monomers.

Abstract: A process and apparatus is for recycling LCO and/or HCO to an FCC unit to recover additional distillate. Spent catalyst recycle in the FCC unit may be used to improve distillate yield. A hydroprocessing zone may saturate cycle oil aromatics for cracking in an FCC unit. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone for hydrotreating feed to the FCC unit. Additional recovery of cycle oil for recycle is obtained by heating slurry oil prior to vacuum separation.

Abstract translation: 一种方法和设备是将LCO和/或HCO再循环到FCC单元以回收另外的馏出物。 可以使用FCC装置中的废催化剂再循环来提高馏出物的产率。 加氢处理区可能会使FCC油循环油芳族化合物在FCC装置中饱和。 再循环裂化的物流可以循环到下游加氢处理区，以避免用于将进料加氢至FCC单元的第一加氢处理区。 通过在真空分离之前加热浆料油来获得用于再循环的循环油的额外回收。

Abstract: Methods and apparatuses are provided for cracking a hydrocarbon. The method includes contacting a first hydrocarbon stream with a first cracking catalyst at a first cracking temperature in a first riser to produce a first riser effluent and a first spent catalyst. A second hydrocarbon stream is contacted with a second cracking catalyst at a second cracking temperature in a second riser to produce a second riser effluent and a second spent catalyst, where the second cracking temperature is less than the first cracking temperature. The first riser effluent and the second riser effluent are combined to produce a mixed riser effluent, and the mixed riser effluent is fractionated in a fractionation zone to produce a light cycle oil. The first spent catalyst and the second spent catalyst are combined in a reactor to produce a mixed spent catalyst.

Abstract: One exemplary embodiment can be a process for extracting one or more sulfur compounds. The process may include mixing a hydrocarbon stream containing the one or more sulfur compounds with an alkaline stream in at least one vessel. Often, the at least one vessel includes a member forming a perimeter about an interior space and having a first side and a second side forming a passageway communicating at least one of the hydrocarbon stream and the alkaline stream from an outer surface of the member to the interior space, and a frustum. The frustum can be positioned proximate to the passageway and abutting the member for facilitating contacting of the hydrocarbon stream and the alkaline stream.

Abstract: Higher temperature regenerated dehydrogenation catalyst is mixed with the lower temperature spent dehydrogenation catalyst from a dehydrogenation reaction to heat the spent catalyst. Air or other oxygen containing gas may be introduced to facilitate mixing. The mixing of hot regenerated catalyst with cooler spent catalyst increases the temperature of the spent catalyst and makes the coke on catalyst and in the supplemental fuel gas instantly ready to combust without the delay necessary to heat up the spent catalyst to combustion temperature. The regenerated dehydrogenation catalyst may be mixed with the spent dehydrogenation catalyst before the mixture of catalyst is contacted with the supplemental fuel gas. Combustion with fuel gas should be conditioned to avoid generation of a flame.
