S&B Wins Chevron Hexane Contract

Read Time: 2 mins

Chevron Phillips Chemical has awarded S&B Engineers and Constructors the contract to build the company’s second US world-scale unit to produce on-purpose 1-hexene in Old Ocean, Texas, near its existing Sweeny facility.

S&B completed Chevron Phillips Chemical’s first US 1-hexene unit in 2014 at its Cedar Bayou plant in Baytown, Texas. The project earned S&B the prestigious Excellence in Construction Award for innovative design, precise craftsmanship, and superior safety performance and practices by Associated Builders and Contractors’ Houston Chapter.

Chevron Phillips Chemical’s new 1-hexene unit will use the latest evolution of the company’s proprietary, on-purpose 1-hexene technology. The new unit will produce up to 266,000 metric tons or (586,000,000 lbs.) per year of 1-hexene, a critical component in high-performance polyethylene (PE). This plastic resin is commonly used in the production of film and rigid containers for a variety of everyday products, including packaging for food, detergent and pharmaceuticals, among many others.

“The S&B team’s experience and track record make them the right contractor for the project as our business expands to meet global demand,” said Mitch Eichelberger, executive vice-president of polymers and specialties at Chevron Phillips Chemical. “We are confident S&B will continue to deliver on its commitments as it has in the past while positively contributing to the local economy.”

S&B anticipates 600 construction and engineering jobs will be created for the project at its peak. Construction will commence during the third quarter of 2021, with project startup expected in 2023. For more information visit:
