FERNANDEZ-FEAL, Coro; FERNANDEZ-FEAL, Luisa; ESCUDERO, Paola y PEREZ-PRADO, José R. Evolution of Sulphur Content in Commercialized Gasoline in Galicia (Spain) as a Result of the Application of the Royal Decree 1700/2003. Inf. tecnol. [online]. 2009, vol.20, n.1, pp.53-65. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642009000100007.
The objective of the study was to determine the sulphur content in gasoline which were commercialized in Galicia six months before and six months after the first of January 2005, the date established by law, according to the royal decree 1700/2003, to reduce the sulphur content in gasoline. This was done to verify the fulfilment of the new legislation starting that date: 150 mg/kg in the period July to December 2004 and 50 mg/kg in the period January to June 2005. The sulphur content in the samples was determined according to a normalized procedure adapted to this type of product. All gasoline samples presented sulphur content lower than the maximum limit established by the legislation. These results show the fast adaptation performed by the refineries in their desulphurization processes to comply with the new legislation.
