摘要： Systems and methods are disclosed for crude oil separation and upgrading, which include the ability to reduce aromatic complex bottoms content in gasoline and higher-quality aromatic compounds. In some embodiments, aromatic complex bottoms are recycled for further processing. In some embodiments, aromatic complex bottoms are separated for further processing.

摘要： Provided here are processes and systems for conversion of alkyl-bridged non-condensed alkyl multi-aromatic compounds to alkyl mono-aromatic compounds. One system includes a hydrodearylation reactor adapted to receive a hydrogen stream and a feed stream and to produce a reactor effluent stream in presence of a catalyst. The feed stream contains one or more of heavy alkyl aromatic compounds and one or more alkyl-bridged non-condensed alkyl multi-aromatic compounds. The reactor effluent stream contains one or more alkyl mono-aromatic compounds. The system also includes a first separator fluidly coupled to the hydrodearylation reactor and adapted to receive the reactor effluent stream and to produce a hydrodearylated gas stream and a hydrodearylated liquid stream. The system also includes a second separator fluidly coupled to the first separator and adapted to receive a portion of the hydrodearylated gas stream and to produce a hydrocarbon liquid stream and a vapor stream rich in hydrogen.

摘要： A method for producing para-xylene (PX) includes introducing a C8 aromatic-containing composition to a xylene rerun column to separate the C8 aromatic-containing composition into a xylene-containing effluent and a heavy effluent and passing the xylene-containing effluent to a PX processing loop that includes a PX recovery unit operable to separate a PX product from the xylene-containing effluent, a membrane isomerization unit operable to convert a portion of the MX, OX, or both from the xylene-containing effluent to PX, an EB dealkylation unit operable to dealkylate EB from the xylene-containing effluent to produce benzene, toluene, and other C7− compounds, and a membrane separation unit operable to produce a permeate that is PX-rich and a retentate that is PX-lean. The permeate is passed to the PX recovery unit for recovery of PX, which the retentate is bypassed around the PX recovery unit circulated through the xylene processing loop.
