  • Patent number: 9283531
    Abstract: A hydrotreater reactor device includes a reactor chamber including a first bed and a second bed. A first input is disposed to provide a hydrocarbon stream to the first bed and a second input is disposed to bypass the first bed and provide a hydrocarbon stream to the second bed. A differential temperature controller measures a temperature difference across the first bed. A control valve at the second input adjusts an amount of the hydrocarbon stream admitted through the second input based on the measured temperature difference. A charge heater provides a hydrocarbon stream as an output through a split output line having a first branch connected to the first input and in fluid communication with the first bed, and a second branch connected to the second input and in fluid communication with the second bed. A restrictor downstream of the split controls a pressure drop at the first input.

  • Publication number: 20140091010
    Abstract: One exemplary embodiment can be a process for removing hydrogen sulfide from a fractionated hydroprocessed effluent. The process can include stripping a hydroprocessed effluent from a hydroprocessing zone, fractionating the stripped hydroprocessed effluent to obtain a naphtha cut, and sending the naphtha cut to a hydrogen sulfide removal zone. The hydrogen sulfide removal zone can include an amine wash settler, an amine contacting column, or a steam stripper.
