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.
