Two-stage hydroprocessing apparatus with common fractionation |
摘要 |
Two-stage hydroprocessing uses a common dividing wall fractionator. Hydroprocessed effluents from both stages of hydroprocessing are fed to opposite sides of the dividing wall. |

1. An apparatus for hydroprocessing hydrocarbonaceous feedstock comprising:
a first hydroprocessing reaction zone for hydroprocessing said hydrocarbonaceous feedstock; a dividing wall fractionation column including a dividing wall extending to a bottom of said dividing wall fractionation column that divides the dividing wall fractionation column into a first side and a second side, said first side being in downstream communication with said first hydroprocessing reaction zone and a diesel bottoms line for removing a diesel stream from the first side; a second hydroprocessing reaction zone in downstream communication with said first side of said dividing wall fractionation column; said second hydroprocessing reaction zone for hydroprocessing a feed diesel stream from said first side of said dividing wall fractionation column; and a second side of said dividing wall fractionation column being in downstream communication with said second hydroprocessing reaction zone and a hydroprocessed diesel line for a hydroprocessed diesel stream to exit the second side, wherein communication is prevented between the diesel bottoms line and the hydroprocessed diesel line. |
