Chevron Phillips Chemical Co. is studying the potential expansion of its normal alpha olefins (NAO) capacity at its Cedar Bayou Chemical Complex in Baytown, Texas.

The company, which is targeting at least a 20-percent capacity increase in a phased approach, said it has filed the necessary environmental permit application with Texas Commission on Environmental Quality (TCEQ).

Construction would begin in the first quarter of 2014 and would be completed in the fourth quarter of 2015.

“This study echoes Chevron Phillips Chemical’s strong commitment to the NAO business and to meeting the growing demand of our customers,” said Mitch Eichelberger, general manager of normal alpha olefins and polyalphaolefins for Chevron Phillips Chemical. “In addition, this proposed expansion has great synergy with the 1-hexene plant currently being built at our Cedar Bayou complex.”

Earlier in 2012, Chevron Phillips Chemical began construction of the world’s largest on-purpose 1-hexene plant capable of producing up to 250,000 metric tons per year at its Cedar Bayou complex. This project is anticipated to start up during the first half of 2014 and utilizes Chevron Phillips Chemical’s proprietary, second generation, on-purpose 1-hexene technology to produce comonomer grade 1-hexene with exceptional product purity from ethylene.
