Ensaio de corrosão acelerado para avaliação do metal formador de tanques de armazenagem de biodiesel

With progress in biodiesel driven by renewable energy matrices, Brazil is at the forefront of using vegetable and animal oil as the automotive fuel. The dynamic production of biodiesel solutions for the production of biodiesel, since the industry in general uses metallic tanks for the development of other fuels with different physical and chemical characteristics. Industrial corrosion is a 30% industry results from installation with subsequent replacement or preventive maintenance. The work sought a methodology to evaluate the corrosion of steel from tanks used for the storage of biodiesel, due to the absence of a specific methodology for the analysis of biodiesel as a corrosion factor. Tests of cloudiness with biodiesel were developed in an experimental machine, as well as immersion tests and electrochemical tests for comparison. A statistical basis for experiment planning was performed. The results were more aggressive than the specified steel, and what is present in the fuel is the factor that has the greatest impact on corrosion.
