The mix of products also depends on the kind of crude oil processed. Heavier crude oils are more difficult to refine into lighter products like gasoline. Refineries that use simpler refining processes may be restricted in their ability to produce products from heavy crude oil. Examples of a Crac...

Crude oils vary dramatically in color, odor, and flow properties. There are light and heavy crude oils; they are sweet or sour (i.e., have high or low sulfur content, with an average of 0.65%). Several thousand compounds are present in petroleum. The number of carbon atoms in these co...
