  • Hydrotreating process and apparatus relating thereto
    Patent number: 9914889
    Abstract: One exemplary embodiment can be a process for treating a hydroprocessing fraction. The process can include obtaining a bottom stream from a fractionation zone, and passing at least a portion of the bottom stream to a film generating evaporator zone for separating a first stream containing less heavy polynuclear aromatic compounds than a second stream.
    Type: Grant
    Filed: March 15, 2017
    Date of Patent: March 13, 2018
    Assignee: UOP LLC
    Inventors: Richard K. Hoehn, Soumendra Mohan Banerjee, David M. Bowman, Xin X. Zhu

  • Process for recovering hydroprocessed hydrocarbons with two strippers in one vessel
    Patent number: 9670424
    Abstract: A process is disclosed for recovering hydroprocessing effluent from a hydroprocessing unit utilizing a hot stripper and a cold stripper. The cold stripper and the hot stripper are contained in the same vessel. A barrier prevents material from the hot stripper from entering into the cold stripper.

  • Process for recovering hydroprocessed hydrocarbons with two strippers
    Patent number: 9518230
    Abstract: A process is disclosed for recovering hydroprocessing effluent from a hydroprocessing unit utilizing a hot stripper and a cold stripper. Only the hot hydroprocessing effluent is heated in a fired heater prior to product fractionation, resulting in substantial operating and capital savings.

  • Process and apparatus for recovering hydroprocessed hydrocarbons with single product fractionation column
    Patent number: 9150797
    Abstract: A hot stripped hydroprocessed stream from a stripper column may be sent directly to a vacuum fractionation column instead of being first processed in an atmospheric fractionation column. If a separate warm stripper column is used, both the warm stripped stream and a hot stripped stream may be fractionated in the same fractionation column, particularly a vacuum fractionation column.

  • Process and apparatus for recovering hydroprocessed hydrocarbons with stripper columns
    Patent number: 9127209
    Abstract: Two or three strippers are used to strip three hydroprocessed effluent streams, perhaps from a slurry hydrocracking reactor, separated by temperature instead of a single stripper to preserve separations previously made and conserving energy and reducing vessel size. A cold stripped stream may be taken as a diesel blending stock without further fractionation.
