Crude Oil FuturesOverviewOil provides about 40 percent of the energy Americans consume and roughly 97 percent of our transportation fuels. Oil is at the crux of the modern economic system, and its importance should not be discounted. Besides meeting almost half of our total energy needs and the lion's share of America's transportation fuel needs, the oil industry employs almost one and a half million people in theUnited States. Not only is Oil, in one form or another, used to heat our homes and fuel our vehicles, petroleum-based products can be found in a variety of everyday household items, including deodorant, toothpaste, paints, balloons, perfumes and cosmetics. Crude Oil in its raw form has to be refined to be used. Distillation is the primary method of refining Crude Oil into its resulting products. The Crude Oil is heated at the bottom of a tall metal tower. As Crude gets hotter, it turns to a gaseous state and the vapors rise. When the vapors rise, they cool. Each Crude Oil by-product, in its gaseous state, has a specific cooling temperature, corresponding with a height of the tower. At these predetermined heights in the tower, pipes lead off to separate the various petroleum products. Heavier fractions, like fuel oils and diesel fuel, are taken from the bottom part of the heating tower. Lighter fractions, like butane, gasoline and kerosene, are taken from the top of the tower. The heating tower produces the rough materials for the six basic categories of petroleum products, which are jet fuel, kerosene, motor gasoline, diesel fuel, residual fuel and distillate fuels. The major use of Crude Oil is for refining into its various products, such as gasoline and heating oil.
