Abstract: Embodiments of apparatuses and methods for hydrotreating coker kerosene or other thermally or catalytically cracked hydrocarbon stream are provided. In one example, a method comprises splitting a feed comprising coker kerosene into first and second feed streams. The first feed stream is heated to form a heated first feed stream. The second feed stream is partially heated to form a partially heated second feed stream. The heated first feed stream is contacted with a first hydrotreating catalyst to form a first hydrotreated intermediate stream. The first hydrotreated intermediate stream is combined with the partially heated second feed stream to form a partially quenched first hydrotreated intermediate combined stream. The partially quenched first hydrotreated intermediate combined stream is contacted with a second hydrotreating catalyst to further hydrotreat the partially quenched first hydrotreated intermediate combined stream.

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.

Abstract: One exemplary embodiment can be a process for hydroprocessing. The process can include providing a hydroprocessing zone having at least two beds, and quenching downstream of a first bed of the at least two beds with a first vacuum gas oil that may be lighter than another vacuum gas oil fed to the first bed.

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.

Abstract: One exemplary embodiment can be a process for washing a gas from a hydroprocessed effluent from a hydroprocessing zone. The process may include adding a first portion of a wash water stream to the hydroprocessed effluent to form a combined stream, condensing the combined stream, adding a first portion of a wash water stream to the effluent to form a combined stream, sending the combined stream to a separator, and providing a second portion of the wash water stream to the tower for washing one or more gases rising in the tower. The separator can include a substantially cylindrical body, in turn, coupled to a boot and a tower.
