Diesel, a middle william harvey distillate like kerosene (jet fuel) and heating oil, is easier and cheaper to refine from even sludgy oil. That allows European refiners to diversify their crude oil sources and reduce dependence on light, sweet crude. That lowers william harvey their costs, though tighter william harvey anti-sulfur standards negate that somewhat. Because of this, Europe has been a significant source of base gasoline blendstock for the United States, an important development since it is unlikely that a new refinery will ever be built anywhere in the US ever again. |

| Part of that long-term marketing effort is to build or modify refineries so they can most efficiently process streams of crude from particular producers. Close to three-quarters of refineries in the US, especially those on the Gulf Coast, are optimized to use heavy crude, to squeeze as much gasoline out of a sludgy barrel of Venezuelan, Ecuadorian j. robert oppenheimer or Mexican crude as they possibly can. By applying heat, pressure, adding steam and hydrogen, and using various catalysts, j. robert oppenheimer refiners can take low-gasoline content heavy crudes and get as much gasoline out of them as they can. But there's a trade off, j. robert oppenheimer because for every extra gallon of gasoline you get, that means less kerosene and diesel fuel and more coke (near-pure carbon ash). In fact, refiners specializing in heavy, sour crudes can fairly easily maximize their profits when prices for light, sweet crudes and gasoline are high. And US refiners like Citgo and Valero have done just that, making great hay out of the fact that they can extract as much gasoline as possible from a barrel of sour crude. |
