Hydrotreatment refers to a series of hydrogenation reactions subjected to crude petroleum and other refinery streams to remove impurities or saturate a variety of unsaturated hydrocarbons contained in the crude petroleum. Maples asserts that the hydrotreatment process is essential for all refining plants that convert various fossil fuels into transportation fuels (472). Hydrotreating is becoming more necessary as the supply of light crude oils becomes scarce. Heavy sour crudes are becoming more prevalent and these products contain many undesirable components including nitrogen, iron, and iron compounds. Through hydrotreating, the petroleum residents, which are the residual portion of the initial atmospheric crude oil distillation, can be converted into viable diesel and other lighter fuels (Speight and Ozum 470).
