Feb. 26 (Bloomberg) -- Royal Dutch Shell Plc had a release of an unknown amount of benzene after an equipment failure on a distilling unit at its Deer Park refinery and chemical plant in Texas, according to a company filing.
Shell’s filing also showed the equipment was repaired.
The Deer Park refinery, a venture between The Hague-based Shell and Mexico’s state-owned Petroleos Mexicanos, can process 340,000 barrels of oil a day, according to data compiled by Bloomberg.
The complex is 21 miles (34 kilometers) southeast of Houston on the Houston Ship Channel.
U.S. refineries must notify the National Response Center if they release hazardous substances in excess of reportable quantities, according to the Comprehensive Environmental Response, Compensation and Liability Act, commonly known as Superfund.
