South Korea’s Daelim Industrial is the front runner for deals to build parts of a giant petrochemical complex owned by state oil giant Saudi Aramco and US Dow Chemical, industry sources said, according to Reuters.

Daelim submitted the lowest bid for the construction projects, which include production for toluene di-isocyanate (TDI), methylene di-para phenylene isocyanate (MDI), dinitrotoluene (DNT), mononitrobenzene (MNB), analine and formaline, sources said.

"I believe it is Daelim, I think it will go to them," one source said. Two other sources told Reuters Daelim was in a "good position" to win the deals.

A Dow spokesperson was unavailable to comment when contacted by the news agency.

While industry sources say the deals are now being finalised, a spokesman from Daelim said recently that "nothing has been confirmed" when asked if Daelim was the lowest bidder.

South Korea’s Samsung Engineering has also bid for the deals. A Samsung Engineering official said no results of the tender have come out yet.

Aramco and Dow are spending $20 billion on the venture – Sadara Chemical Co – to build one of the world’s largest petrochemical facilities in Jubail on the Gulf coast.
