Description:

Petroleum refineries in many countries are facing the challenge of producing motor gasoline having all the desirable properties while complying with the ever increasing environmental regulations. Today, more stringent regulation is challenging refiners to meet the tightening gasoline specifications for benzene at the lowest cost and without significant octane loss. For instance, the United States Environmental Protection Agency's most recent clean fuels regulations (Mobile Source Air Toxics II) require refineries to reduce benzene to less than 0.62 vol% (on an annual basis) in gasoline by 2011, from its current level of 1.0 vol%. The limits apply to both reformulated and conventional gasoline. The fuel regulation also includes a nationwide averaging, banking, and trading (ABT) program to provide early incentives for refiners to achieve lower benzene before the regulations become effective. Beginning July 1, 2012, importers and most refineries are required to import or produce gasoline with a maximum annual average gasoline benzene content of 1.3 vol%. A refinery's or importer's actual annual average gasoline benzene level may not exceed this maximum average standard and credits may not be used to meet the 1.3 vol% standard.
