  • Spans two sites: Jurong (Pioneer Road) and Pulau Ayer Chawan (Jurong Island), connected by pipelines
  • Produces: Gasoline, diesel, jet fuel, LPG, asphalt, base oils, waxes, aromatics
  • Supplies feedstock to the chemical plant

Singapore Chemical Plant

• Olefins Plant
  • Produces: Ethylene, propylene, polyethylene, polypropylene, butyl rubber, oxo alcohols, aromatics, hydrogenated hydrocarbon resins, specialty polymers
  • Key units: Olefins plant, polyethylene plant, polypropylene plant, elastomers plant, resins plant, butyl plant, oxo-alcohol plant
  • Production capacities:
    • Ethylene: 1,900 KTA
    • Butene-1: 100 KTA
    • Butenes: 450 KTA
    • Motor gasoline: 950 KTA
• Singapore Polyethylene Plant (SPE)
  • PE is one of the world’s largest capacity polyethylene extrusion and pelletizing line that utilizes cutting-edge ExxonMobil GPPT.
  • Production capacity: 1,900 KTA
• Singapore Polypropylene Plant
  • The plant is among the world’s highest capacity, using the ExxonMobil Polypropylene Technology for producing homo-polymer and impact co-polymer  resins. ExxonMobil also licenses this proprietary innovation, which is a pioneering integration of polypropylene slurry and gas phase technologies.
  • Production capacity: 930 KTA
• Singapore Elastomer Plant
  • The plant uses ExxonMobil proprietary catalyst technology in combination with solution polymerization process.
  • Production capacity: 300 KTA
• Aromatics Plant
  • Jurong Aromatics Recovery [JAR]
    • JAR uses ExxonMobil state-of-the-art xylene isomerization Xymax^SM technology and heavy aromatics transalkylation TransPlus^SM technology. In addition, it also uses other advanced technologies to recover paraxylene and benzene.
    • Production capacities: 
      • Paraxylene: 1,800 KTA
      • Benzene: 1,300 KTA
      • Orthoxylene: 406 KTA
  • Singapore Aromatics Recovery [SAR] and SCP Banyan Facility [SAR2]
    • ExxonMobil completed the acquisition of one of the world’s largest aromatics facilities on Jurong Island in August 2017. This plant is now known as the SCP Banyan Facility (SAR2).
    • Singapore Aromatics Recovery (SAR) and SCP Banyan Facility (SAR2) use ExxonMobil’s state-of-the-art xylene isomerization XymaxSM technology and other advanced technologies to recover paraxylene and benzene.
    • The acquisition adds operational and logistical synergies, as well as increases ExxonMobil’s Singapore aromatics production to over 3.5 million tonnes per year, including 1.8 million tonnes of paraxylene, plus an additional 65,000 barrels per day of transportation fuels capacity.
• Singapore Halobutyl rubber
  • Producing bromobutyl and chlorobutyl rubbers
  • Production capacity: 140,000 tonnes per year
• Singapore Resins Plant
  • The hydrogenated hydrocarbon resin production unit – which incorporates ExxonMobil’s proprietary technology – is the world’s largest at this time.
  • Production capacity: 90,000 tonnes per year
• Singapore Oxo-Alcohol Plant
  • Fed by the butylene stream from the steam cracker the Oxo-Alcohol Plant utilizes ExxonMobil Cobalt Flash Technology to
    produce oxo alcohols through hydroformylation.
  • Production capacities:
    • Iso-nonyl Alcohol: 345 KTA
    • Isopar Fluids: 35 KTA

Lubricant Plant

• Largest ExxonMobil lubricant plant in Asia Pacific for greases
• Produces: basestocks, which are then processed into finished lubricants (e.g. Mobil 1 engine oil) and greases at a nearby plant
• Production capacity: 44 KBD

Fuels Terminal & LPG Bottling Plant

• Fuel production including LPG, Naphtha, Motor Gasoline, Kerosene (Jet Fuel), Gas Oil/Diesel, Heavy Fuel Oil Residual
• Production capacity: 427 KBD
• Supports distribution of fuels and LPG for commercial and domestic use

Cogeneration Facilities

• Three cogeneration units generating ~440 megawatts of electricity
• Provide power and steam, enhancing energy efficiency
