  • Publication number: 20240010937
    Abstract: A solvent stripping process has been developed for separating the pyrolysis oil in an extracted phase feed stream from an organic solvent used for extraction. The process involves using a stripping solvent to strip the organic solvent from the pyrolysis oil in a stripping column. The stripping column bottom stream comprising the pyrolysis oil and part of the stripping solvent can be separated into a vapor stream comprising the stripping solvent and a liquid stream comprising the pyrolysis and a portion of the stripping solvent. The stripping column overhead stream comprising the stripping solvent and the organic solvent can be separated in a recovery column into a recovery column overhead stream comprising the stripping solvent and a recovery column bottom stream comprising the organic solvent.

  • Patent number: 11027221
    Abstract: The present invention relates to dual extract flush for feeds for xylene extraction processes. More specifically, the present invention relates to dual extract flush for feeds for simulated moving bed extraction processes. It decouples line flush in and line flush out, providing a means for optimizing each flush independently. This scheme will allow for minimizing each bedline and flushing each according to its own bedline volume, which will minimize any additional non-ideal compositions added to the chambers or downstream fractionation.

  • Publication number: 20200354293
    Abstract: Processes for recovering para-xylene from a para-xylene separation zone that receives two or more feed streams with different para-xylene amounts. One of the feed streams may have an equilibrium amount while the second may have a high amount. A fractionation column provides the effluent stream with para-xylene which may be a high purity stream that can be fed to the para-xylene separation zone in its entirety. If heavier compounds need to be removed from the second feed stream, a split shell or divided wall column may be used.

  • Patent number: 10822291
    Abstract: Processes and apparatuses for producing a C8 aromatic isomer product are provided. The processes comprise introducing a raffinate product stream comprising C8 aromatic isomers to an isomerization unit to provide an isomerized stream. The isomerized stream is separated to provide a first stream comprising C8 naphthenes and C7 aromatic hydrocarbons and a second stream comprising C8 aromatic isomers. The first stream is passed to an extractive distillation column to provide a recycle feedstream comprising the C8 naphthenes and an extract stream comprising the C7 aromatic hydrocarbons. The recycle feedstream is passed to the isomerization unit.

  • Patent number: 10577293
    Abstract: Processes and apparatuses for producing para-xylenes are provided. The processes comprises providing a hydrocarbon stream comprising C7+ hydrocarbons. The hydrocarbon stream is separated to provide a C8 aromatics stream and an ortho-xylene rich stream. The C8 aromatics stream is passed to a para-xylene separation unit for separating para-xylene to provide a para-xylene stream and a raffinate stream. At least a portion of the raffinate stream is passed to a first isomerization unit to provide a first isomerization effluent, wherein the first isomerization effluent is produced in the presence of an ethylbenzene (EB) isomerization catalyst. At least a portion of the ortho-xylene rich stream is contacted with an isomerization catalyst in a second isomerization unit in liquid phase at isomerization conditions in substantial absence of hydrogen to produce a second isomerization effluent.

  • Publication number: 20190062240
    Abstract: The present invention relates to a process and apparatus for dual feed para-xylene extraction heavy desorbent and light desorbent aromatics complex flow scheme. More specifically, the present invention relates to a process and apparatus for dual feed para-xylene extraction heavy desorbent and light desorbent aromatics complex flow scheme that takes advantage of the separation efficiency already achieved by toluene methylation or toluene disproportionation processes by sending the high concentration para-xylene to xylene feed to the corresponding concentration position in the para-xylene extraction unit. This enables further para-xylene separation and recovery that can be done with greater energy and capital efficiency.
