Construction on the expansion began in 2013, and it has been completed with the addition of a tenth furnace to ethylene unit 33 at the Sweeny complex, the company said in a statement.
The latest expansion is expected to increase annual ethylene production at the Sweeny complex by 200 million pounds.
The Sweeny complex is one of the world’s largest single-site ethylene facilities and its capacity has now increased to roughly 12 million pounds of ethylene per day, or 4.3 billion pounds annually.
"This represents the next increment of expansion to our ethylene business. We’re building toward the start-up of the US Gulf Coast Petrochemicals Project in 2017 and supporting incremental growth of our olefins derivative businesses," said Dave Smith, olefins and natural gas liquids vice president for Chevron Phillips Chemical.
Chevron Phillips Chemical’s US Gulf Coast Petrochemicals Project includes the construction of an ethane cracker at the company’s Cedar Bayou plant in Baytown, Texas and two polyethylene units in Old Ocean, Texas near the Sweeny complex.
As MRC reported earlier, in July 2014, Chevron Phillips Chemical (CPChem) received approval from its board of directors and obtained an environmental permit from the Texas Commission on Environmental Quality (TCEQ) to expand normal alpha olefins (NAO) production capacity at its Cedar Bayou plant in Baytown, Texas. This investment will provide an additional 100,000 tpy of capacity. Construction completion is anticipated in July, 2015.
Chevron Phillips Chemica, headquartered in The Woodlands, Texas (north of Houston), US,l is one of the world’s top producers of olefins and polyolefins and a leading supplier of aromatics, alpha olefins, styrenics, specialty chemicals, piping, and proprietary plastics. Chevron and Phillips 66 each own 50% of Chevron Phillips Chemical.
