Trabalho de Conclusão de Curso (Graduação em Química) - Instituto de Química, Universidade Federal do Rio Grande do Norte, Natal - RN, 2015.https://repositorio.ufrn.br/handle/123456789/38258The oil industry is affected by formation of scale and corrosive deposits that can disturb oil production as they may reduce the flow of oil, wear pipes down, etc., thus, causing increased costs for removal being it physical removal or the use of chemicals inhibitors for the removal and control of difficult to remove deposits. Prevention is the most viable solution, given that, there is a growing need to understand how the formations happen and their characterization as far as the elements that constitute it are concerned and how these same elements are associated with each other. For the samples selected for this study the following techniques were chosen: Soxhlet extraction, X-Ray Fluorescence Spectrometry (XRF), X-Ray Diffraction (XRD). Also, 6 samples were chosen to this work. Through theses analysis samples associated with incrusting and corrosive products were detected, such as: sulfide in the forms of iron sulfide (FeS); Macknawita (FeS) and Pyrite (FeS2); Carbonates as a calcite magnesium (CaMg (CO3)); Iron carbonate (FeCO3), and zinc carbonate (ZnCO3), as well as the formation of oxides associated with iron like Magnetite (Fe3O4).openAccessResíduos - MonografiaResiduesExtração Soxhlet - MonografiaSoxhlet extractionEspectrometria por Fluorescência de Raios X (EFRX)- MonografiaX-Ray Fluorescence Spectrometry (XRF)Difração de Raios-X (DRX).
