摘要

储罐中液体的均匀性评估对于产品质量控制、商业关系和石油行业面临的重大技术挑战至关重要。本研究描述了巴西石油工业中用于估计大型储罐中是否存在显著（垂直）离析的方法。在这里，使用了一种基于实验设计和经典方差分析的方法来分析实验数据，以获得更好的方法来估计储罐内是否存在统计上显著的偏析（在本文中，缺乏显著性被称为同质性）。尽管方差分析是一种适用于此目的的工具，但对结果进行了更详细的分析，以提出一种可常规使用的实用方法。机械地使用方差分析检验可能很容易导致错误的结论。

Assessment of liquids homogeneity in storage tanks in the oil industry through the comparison of uncertainties

The assessment of homogeneity of liquids in storage tanks is crucial for quality control products, commercial relations and a salient technological challenge facing the petroleum industry. This study describes a method used in the Brazilian oil industry to estimate if there is significant (vertical) segregation in large storage tanks. Here, a method based on experimental design and classical ANOVA for analyzing the experimental data to arrive at a better method to estimate if there is statistically significant segregation within the storage tanks (lack of significance is called homogeneity in the paper) was used. Although ANOVA is a suitable tool for this purpose, the results were analyzed in more detail to propose a practical method that can be used routinely. Mechanical use of the ANOVA tests may easily lead to wrong conclusions.

期刊介绍： Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
