Although every refinery pumps up crude oil from all around the world, there are different kinds of crude oils. Crude oils that are less dense relative to others are usually richer in hydrocarbons, the key factor in combustion. This kind of crude oil is much easier to refine because it only requires simple distillation processes. However, more dense crude oils, which normally contain more sulfur, require much more complicated distillation and refining process. To treat these high density oils, refineries use a Coker. Coker is called a “thermal cracking unit” (Chevron El Segundo Refinery) because this unit uses high heat to “crack” heavy material into lighter materials, such as gasoline, jet fuel, and diesel. Meanwhile, after these fuels
