The properties of fuel oil mainly depend on the nature of crude oil and processing methods, and the main specifications that determine the quality of fuel oil include viscosity (Viscosity), sulfur co
ntent (Sulfur Content), pour point (Pour Point) and other fuel oil for use in power plants, etc. There are also regulations on the co
ntent of vanadium (Vanadium) and sodium (Sodium).
Most petroleum products can be used as fuel, but fuel oil has different interpretations in different regions. The European concept of fuel oil generally refers to the black viscous residue left by the distillation of crude oil, or its blend with lighter components, which is mainly used as fuel for steam furnaces and various heating furnaces or as large-scale slow Fast diesel fuel and as a variety of industrial fuels. But in the United States, it refers to any combustible liquid or liquefiable petroleum product with a flash point of not less than 37.8°C. It can be either Residual Fuel Oil (also known as Heavy Fuel Oil) or distillate fuel oil ( Heating Oil). Distillate fuel oil can not only be obtained directly from distilled crude oil (ie straight-run distillate), but also can be obtained from other processing processes such as cracking and then distillation.
