  • Patent number: 9950972
    Abstract: Apparatuses and methods are provided for forming C8 aromatic streams with selected amounts of C9 aromatics. In one embodiment, a method for forming a C8 aromatic stream with a selected amount of C9 aromatics includes fractionating a hydrocarbon stream including C8 and C9 aromatics into a sidedraw fraction and a bottom fraction. The sidedraw fraction includes a portion of the C8 aromatics and a portion of the C9 aromatics. The bottom fraction includes remaining C8 aromatics and C8+ hydrocarbons. The method further includes fractioning the bottom fraction and forming a heavy overhead fraction including the remaining C8 aromatics. Also, the method includes combining the sidedraw fraction and the heavy overhead fraction to form a combined stream having a C9 aromatics composition of from about 0.1 wt % to about 5 wt % about 2 wt % of a total weight of the combined stream.

  • Patent number: 9302955
    Abstract: Methods and systems are provided for separating a selected xylene isomer. The method includes separating a feed stream including a plurality of aromatic hydrocarbons into a first stream including toluene and isomers of xylene, and a second stream including isomers of xylene. The method further includes separating the first stream into a third stream including toluene and a fourth stream including isomers of xylene. The method further includes combining the second stream and the third stream in an adsorptive separation unit including an adsorbent configured to adsorb the selected xylene isomer from the second stream. The third stream desorbs the selected xylene isomer to produce a fifth stream including the selected xylene isomer and toluene and a sixth stream including non-selected xylene isomers and toluene. Still further, the method includes separating the sixth stream into a seventh stream including the non-selected xylene isomers and the third stream including toluene.
