Abstract

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.

生物柴油储罐形成金属评价的加速腐蚀试验

随着可再生能源驱动的生物柴油的发展，巴西在使用植物油和动物油作为汽车燃料方面走在了前列。生物柴油的动态生产为生产生物柴油提供了解决方案，因为该行业一般使用金属罐来开发其他具有不同物理和化学特性的燃料。30%的工业腐蚀是由安装和后续更换或预防性维护造成的。由于缺乏分析生物柴油作为腐蚀因素的具体方法，这项工作寻求一种方法来评价用于储存生物柴油的储罐的钢的腐蚀情况。在实验机上对生物柴油进行了浊度试验，并进行了浸泡试验和电化学试验进行比较。为实验计划提供了统计学依据。结果比指定的钢更具侵蚀性，而燃料中存在的是对腐蚀影响最大的因素。
