Oil can be used in so many ways other than fuel because it contains hydrocarbons of varying molecular masses, forms and lengths such as paraffins and aromatics used in pharmaceutical industry. The differences in the structure of these molecules is what gives them their varying physical and chemical properties, and it is this variety that makes crude oil so useful in a broad range of applications. Consequently, the refining process releases numerous different chemicals into the atmosphere. Also, substantial air pollution emissions and poisonous gases accompany the presence of a refinery. Aside from air pollution impacts, there are also wastewater concerns, risks of industrial accidents such as fire and explosion, and health effects due to industrial noise. Because of environmental and safety concerns, it should be noted that oil refineries be located some distance away from major urban areas. Nevertheless, there are many instances where refinery operations are close to populated areas and cause numerous risks along with their invaluable productions.
