The Chevron Phillips Chemical Sweeny Complex has been in operation since 1944. Located 50 miles southwest of Houston, the facility is adjacent to the Phillips 66 Refinery. The Sweeny Complex is one of the world’s largest single-site ethylene facilities, capable of producing over 11 million pounds of ethylene per day. In addition to ethylene and propylene production, the Sweeny Complex has salt dome storage operations at the Clemens Terminal located 12 miles south of the facility.
Two world-scale polyethylene units started up in 2017 at the Old Ocean facility adjacent to the Sweeny Complex. The new units are each capable of producing 500,000 metric tons — 2.2 billion pounds — of plastic resin annually. The Old Ocean Rail Operation Facility supports the new polyethylene units with full and empty railcar storage and staging, railcar maintenance, and other transportation functions. At a length of five miles, it has the capacity to store over 1,500 railcars. The new Chevron Phillips Old Ocean Warehouse serves the ethylene, polyethylene and NGL units to provide bagging and tagging of daily maintenance, project material, and storage of critical spares, consumables and tools.
