Chevron Phillips Chemical Co. LP (CPChem) is expanding the normal alpha olefins (NAO) production capacity at its Cedar Bayou plant in Baytown, TX. The expansion, which is intended to take advantage of low-cost shale gas supplies, will add 100,000 metric tons per year of capacity and is expected to be completed in July 2015. The project has been permitted by the Texas Commission on Environmental Quality. NAOs and derivatives are used extensively as polyethylene co-monomers, synthetic motor oils, lubricants, automotive additives and in a wide range of specialty applications.
