Tesoro to launch new petrochemical feedstock project Tesoro announced plans to produce petrochemical feedstock in its U.S. West Coast refining system. The company intends to gather intermediate feedstock, primarily reformate, from its West Coast refining system for xylene extraction at Anacortes, Washington. The initial investment, estimated to be around $400M, is designed to recover up to 15K barrels per day of mixed xylene. The mixed xylene will mainly be exported to Asia and is used to make polyester fibers and films for clothing, food packaging and beverage containers. The project is expected to generate competitive returns similar to other recent capital projects by Tesoro. Startup of the new facilities is expected to be in 2017. A final investment decision is expected by year-end.
