AM-99-44 REFINERYWIDE IMPLICATIONS OF PRODUCING LOW-SULFUR FUELS

Description:

Within the next few years, European and U.S. governmental regulations will require refiners to significantly lower the sulfur content of gasoline as part of the continuing effort to reduce air pollution from gasoline engines. Sulfur is targeted because it significantly reduces the efficiency of automobile catalytic converters. Similarly, governments are considering, or have recently mandated, changes to diesel fuel specifications, again requiring lower sulfur levels than current specifications. Emissions of SO2 and other contaminants from fluid catalytic cracking (FCC) regenerator and refinery heater stacks continue to be an issue with refiners throughout the United States and the rest of the world.
