  • Patent number: 9267083
    Abstract: Processes are provided herein for producing naphtha boiling range products with a desired sulfur content by reducing the mercaptan content of the naphtha boiling range products after the products exit a hydroprocessing stage. Due to mercaptan reversion, naphtha boiling range products that contain even small amounts of olefins can have a higher than expected sulfur content after hydroprocessing. In order to reduce or mitigate the effects of mercaptan reversion, microchannel reactors (or microreactors) can be placed in a processing system downstream of a reactor that produces a low sulfur naphtha product. The microreactors can include a coating of metals that have activity for hydrodesulfurization. By passing at least a portion of the naphtha product through the downstream microreactors, the mercaptans formed by reversion reactions can be reduced or eliminated, resulting in a naphtha product with possessing a very low sulfur content.

  • Publication number: 20150001129
    Abstract: A process and apparatus is disclosed for pretreating a hydrocarbon stream in a hydrotreating reactor and separating the diesel materials from the pretreated effluent before the heavier liquid materials are fed to a hydrocracking unit. Thus diesel materials are preserved but recovered along with the hydrocracked effluent. A recovered diesel stream can be sent to a hydrotreating unit to improve its cetane rating.

  • Publication number: 20140262942
    Abstract: Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor seventies and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.

    Abstract: Multiple grades of lube oil base feedstock are produced within a two-stage hydrocracking unit. Effluent from a first hydrocracking zone is sent to a separation zone, which includes multiple separation vessels, and a heavy liquid stream enters one cell of a dual cell fractionator charge heater and is flashed in the distillation zone of a divided wall fractionation column. A portion of the bottom stream from one side of the divided wall column is sent to the second hydrocracking zone. Feed to a second cell of the dual cell fractionation column is derived from the effluent of this second hydrocracking zone. A different lube oil base feedstocks is derived from each of the cells of the dual cell fractionation column.
