Sulfur, Octane, And Petrochemicals

17:30 - 00:00

  • Novel method to segregate sulfur species together with aromatics from cracked gasoline, away from the olefins and other non-aromatics
  • Only the aromatic/sulfur fraction is subjected to HDS, which avoids any olefin saturation
  • Purified aromatics can go to paraxylene production, or re-blended into gasoline
  • Olefin-rich fraction can be re-cracked into propylene; aromatized into BTX; or re-blended into gasoline with no change in octane value
  • Low-cost drop-in solution for systems which already have selective hydrodesulfurisation of FCC gasoline
