Saudi petrochemicals heavyweight Sabic and ExxonMobil have started commercial operation of the first unit within a 400,000 tons/year elastomers plant at Jubail on Saudi Arabia’s Gulf coast.

Sabic says the firms’ Kemya JV has completed trial operations of the carbon black unit within the elastomers plant, which it began commissioning in December. When fully onstream, the plant will also produce halobutyl rubber and specialty elastomers.
