Plant processes

This plant uses pyrolysis gasoline (PG) as feedstock, and sulfolane, the hydrogenated and extractant, to selectively fractionate aromatic raffinate, and then high-purity benzene, toluene and xylene.

  • Gasoline Hydrogenation Unit
    To produce high-purity products, this unit hydrogenates the double-bond compounds in the high-purity feedstock to make saturated compounds, and removes sulfur compounds and turn them into feedstock suitable for the extraction unit.
    It sends the hydrogenated HEART CUT mixed C6~C8 to the extraction unit, and Raw-C5 is used as feedstock for the C5 plant, whereas C9+ is used as feedstock for the hydrodealkylation unit (HDA).
  • Extraction Unit
    This unit selectively extracts aromatic compounds, among the C6~C8 mixture(HEART CUT), that dissolve well in sulfolane, an extractant. The extracted aromatic compounds are sent to the fractionation unit.
  • Fractionation Unit
    This unit uses the difference in boiling points of aromatic mixture coming from the extraction unit and hydrodealkylation unit to produce high-purity benzene, toluene and xylene.
  • Hydrodealkylation Unit
    This unit turns the C9+ mixture fractionated in the hydrogenation unit into aromatic mixture containing lots of benzene through hydrocracking and hydrodealkylation. This aromatic mixture containing a lot of benzene is sent to the fractionation unit.
Product uses

Raw-C5 is produced at the aromatic plant and utilized as the raw material for petroleum resin, isoprene and DCPD.
