HOUSTON (Reuters) - Saudi Aramco <IPO-ARMO.SE> is studying a multi-billion dollar plan to build a petrochemical plant at the Port Arthur, Texas, refinery operated by its subsidiary Motiva Enterprises LLC [MOTIV.UL], sources familiar with the company's plans said on Saturday.
Aramco is scheduled on Saturday to sign agreements in Houston with Honeywell UOP <HON.N> to study an aromatics unit and with Technip FMC <FTI.N> for a unit to produce polymers from ethane, the sources said.
The aromatics unit Honeywell UOP is studying would convert benzene and paraxylene, byproducts of gasoline production, into 2 million tons annually of feedstocks for chemicals and plastics, according to the sources.
The unit Technip FMC is studying would convert ethane into 2 million tons a year of ethylene, which is used to make plastics, the sources said.
The agreements with the two companies include technology licenses for proprietary systems they produce, the sources said.
