  • Heat integration in disproportionation or transalkylation processes
    Patent number: 10472305
    Abstract: Toluene disproportionation and C9/C10 transalkylation are a significant source of xylenes in a modern aromatics complex. Methods and apparatuses for improving the energy efficiency of these disproportionation and transalkylation processes are provided.
    Type: Grant
    Filed: August 5, 2015
    Date of Patent: November 12, 2019
    Assignee: BP Corporation North America Inc.
    Inventors: Craig Colling, Brian Slusar
  • Process for recovering paraxylene from at least two feedstreams containing xylene isomers
    Patent number: 10351491
    Abstract: Processes for recovering paraxylene from at least two feedstreams containing xylene isomers. The process includes directing to a paraxylene recovery zone comprising at least one crystallization zone, a paraxylene-lean feedstream having a paraxylene to total xylene isomer ratio of 0.50 or less, and also directing to the paraxylene recovery zone, a paraxylene-rich feedstream having a paraxylene to total xylene isomer ratio of greater than 0.50. A paraxylene-containing product stream is recovered from the paraxylene recovery zone having a paraxylene to total xylene isomer ratio greater than that of the paraxylene-rich feedstream. The process provides improvements in paraxylene recovery efficiency and/or cost effectiveness.
