INEOS Oligomers starts up the world’s largest single train Low Viscosity Polyalphaolefin (LV PAO) plant at its Chocolate Bayou facility in Texas.


  • The new 120,000 tonne per annum Low Viscosity Polyalphaolefin (LV PAO) unit at Chocolate Bayou, TX is the world’s largest single PAO train.
  • The new LV PAO plant will meet increased demand for improved efficiency from low viscosity low volatility engine oils, electrical transmission fluids and heat transfer fluids for data servers and electrical batteries.
  • It positions INEOS Oligomers as the world’s largest merchant supplier of LV PAO

INEOS Oligomers has today announced that it has started up its new 120,000 tonne per annum Low Viscosity Polyalphaolefin (LV PAO) unit at Chocolate Bayou, TX.  This facility is the world’s largest single PAO train and complements existing units in La Porte, TX and Feluy, Belgium.

It positions INEOS Oligomers as the world’s largest merchant supplier of LV PAO with an unprecedented production footprint in LV PAO. Facilities operated across 3 distinct locations, provide stronger security of supply to the global lubricants industry.

The new Chocolate Bayou LV PAO unit is fully integrated into INEOS’ production of Linear Alpha Olefin (LAO), the raw material used for PAO. Its feedstocks are also supplied from the adjacent LAO plant that started up in 2020 and from its Joffre, Canada LAO unit.

Peter Steylaerts, Business Director INEOS Oligomers said “Our new LV PAO unit comes at the right time to fulfil increasing needs from the lubricant industry for low viscosity low volatility engine oils, electrical transmission fluids and heat transfer fluids for data servers and electrical batteries. It also brings state of the art technology allowing a step change in efficiency of production.”

LV PAOs are used in various lubricants such as engine oils, gear oils, transmission fluids, hydraulic fluids and greases. They offer excellent thermal and oxidative stability, better flow properties and better energy efficiency leading to reduced fuel consumption, reduced emissions, less frequent oil changes and improved reliability of machineries. They are also used in other applications such as processing aids, polymer modification and cosmetics.
