The company will construct new units and modify existing facilities at its Baton Rouge, Louisiana; Baytown, Texas; and Antwerp, Belgium, refineries. This investment is the latest phase in ExxonMobil's efforts to increase supplies and reduce the sulfur content of both motor gasoline and diesel. In 2000, the company began an integrated approach to convert and modify refineries, terminals and pipelines to provide ultra low sulfur fuel products. By 2010, the refineries' modifications and expansions are expected to be completed, increasing production of diesel with sulfur levels of 15 parts per million or less. Sherman Glass, president of ExxonMobil Refining & Supply, said: "This underscores the company's ongoing commitment to meeting the growing needs of the marketplace, while, at the same time, providing cleaner burning fuels to consumers. Our increase in diesel production at these three sites will be equal to the diesel produced from about four average-size refineries."
