ExxonMobil Chemical will build a world-scale facility to manufacture its metallocene polyalphaolefin (mPAO) synthetic lubricant base stocks at its integrated refining and chemical complex in Baytown, Texas. Upon completion, the facility will have the capacity to produce 50,000 tons of high-viscosity (Hi-Vis) SpectraSyn Elite mPAO per year. Engineering, procurement and construction activities for the new facility are currently underway and completion is expected by 2013. SpectraSyn Elite mPAO base stocks are manufactured using a proprietary metallocene catalyst process that offer improved performance characteristics when compared to conventional PAO. The result is finished lubricants with improved shear stability, viscosity index (VI) and low-temperature performance.
