Abstract: A process and apparatus for recycling LCO and/or HCO to a hydroprocessing zone to saturate aromatics for cracking in an FCC unit is disclosed. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone that is primarily for demetallizing (and desulfurizing) feed to the FCC unit.

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.

Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons are provided herein. In one example, a method comprises burning fuel gas to form a hot flue gas and heat a reforming-zone feedstock that contains (C5-C11) hydrocarbons to form a heated reforming-zone feed stream. The heated reforming-zone feed stream is partially reformed to form a partially reformed effluent. The partially reformed effluent is advanced through a process heat recovery coil arrangement that is recovering heat from the hot flue gas to form a heated partially reformed effluent. The heated partially reformed effluent is contacted with reforming catalyst at reforming conditions effective to form a reforming reaction-zone effluent. The reforming reaction-zone effluent comprises H2, C5+ hydrocarbons including aromatics, and C4− hydrocarbons.

Abstract: A process for hydrotreating a feed stream comprising a biorenewable feedstock is disclosed. The process comprises hydrotreating the feed stream in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to provide a hydrotreated stream. The hydrotreated stream is separated into a hydrotreated liquid stream and a hydrotreated gas stream. The hydrotreated liquid stream is subjected to stripping to provide a stripper off-gas stream. At least a portion of the stripper off-gas stream is contacted with a caustic stream to provide a sulfur-lean gas stream and a sulfur-rich caustic stream. The sulfur-rich caustic stream is further treated to provide a treated gas stream.

Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A stripping column for fractionating a dehydrogenation stream is coupled with a demethanizer column for fractionating a pyrolyzed stream. The stripping overhead stream comprising C2− hydrocarbons are fractionated with the pyrolyzed stream in the demethanizer column. The coupling omits the need for a conventional deethanizer column and separate refrigeration system in the propane dehydrogenation unit.
