The Challenges Opportunities of 10 ppm Sulfur Gasoline

摘要

The worldwide refining industry has undergone a major transformation in the last decade due to changes in regulatory and market forces such as fluctuating crude prices, tighter regulation on product quality and refinery emissions, shifting crude quality and fundamental changes in fuel demands. These forces can be seen clearly in the North American market where crude quality has become heavier due to increasing amounts of lower cost heavy, sour Canadian bitumen and where regulations have become more severe by limiting the sulfur level in fuels to 15 wppm in diesel and 30 wppm in gasoline. In addition to these feed and product quality changes the overall transportation fuels demand is shifting from a traditionally gasoline-oriented to increasingly diesel-oriented market.
