Hydrocarbon mixtures are produced in refineries by distillation from natural gas petroleum and natural gas as well as by thermal cracking of higher boiling predominantly hydrocarbon fractions. The individual hydrocarbons differ both in the total number of carbon and hydrogen atoms in their molecules and in the proportion of hydrogen to carbon, and can be divided into various homologous series.

The flash point is an important physical property used to estimate the fire hazard of a flammable liquid.

The flash point is an important indicator for the flammability of the liquid materials and also in the development of safe practices for handling and storage of these materials.

The flash point of fuel is the minimum temperature at which the fuel gives off sufficient vapor to form a flammable mixture above the liquid within a vessel (vapor has reached LFL). Operating at temperatures lower than the flash point of the liquid fuel will not lead to a flammable mixture being formed unless a mist cloud (e.g. due to splashing) is generated.
