Physical and chemical treatments to prevent the growth of microorganisms in diesel fuel storage tanks

The use of petroleum fractions by some microorganisms as a food source has been known for years. This property has been applied mainly in the bioremediation of soils contaminated with hydrocarbons. Nevertheless, this natural degradation of hydrocarbons by microorganisms, has become a serious problem for the oil industry, since it has been observed that microbial growth occurs inside the fuel storage tanks. This fact is causing problems such as corrosion, filter plugging or blockage of pipes. Ultraviolet radiation, sonication and biocides treatments are alternatives to solve the problem.
