HOUSTON, June 21 -- S-Oil Corp. has started a project aimed at increasing paraxylene production at its 520,000 b/cd Onsan refinery and chemical complex in South Korea.
The company has selected ExxonMobil Chemical Technology Licensing LLC's selective PxMax technology, which will allow for an 8% capacity increase without requiring modification of the paraxylene separation process facilities.
The PxMax method produces a paraxylene-enriched mixture that is further processed into sales grade paraxylene. It replaces a nonselective toluene disproportionation process that produced equilibrium mixed xylenes.
