Chevron Phillips Chemical Co. received board approval and obtained the necessary environmental permit from the Texas Commission on Environmental Quality to expand normal alpha olefins production capacity at its Cedar Bayou plant in Baytown, Texas. The expansion will provide an additional capacity of 100,000 metric tons per year.

Construction is expected to be complete in July 2015. S&B Engineers and Constructors Ltd. will perform the engineering, procurement and construction, and expects to support up to 600 jobs during the construction phase.

“This investment decision reflects Chevron Phillips Chemical’s strategy to leverage North American shale gas development by continuing to grow our U.S.-based olefins and polyolefins footprint,” said Mark Lashier, executive vice president of olefins and polyolefins. Normal alpha olefins and its derivatives are used extensively as polyethylene comonomers, synthetic motor oils, lubricants, automotive additives and in a wide range of specialty applications.
