Studies of corrosion caused by naphthenic acids are interfered by presence of other corrosive agents contained in real crude oils, so naphthenic phenomenon must be isolated using synthetic crude oils. For this reason, in present work two high purity mineral oils were used to evaluate their efficiency as synthetic crude oil matrices in AISI/SAE–1020 steel naphthenic corrosion study. Temperature levels evaluated were 200 °C, 250 °C, and 300 °C, while exposure times evaluated were 5, 10 and 15 hours. Surface morphological characterization of AISI/SAE–1020 steel was carried out using scanning electron microscopy and X–ray diffraction. Gravimetric tests showed that AISI/SAE–1020 steel naphthenic corrosion rate increases with temperature and exposure time for one of the synthetic crude oils. However, results obtained for the other synthetic crude oil did not show increasing behaviour due to presence of sulfur traces in the oil, which caused an interference with AISI/SAE–1020 steel naphthenic corrosion study, reducing the reliability of gravimetric results so they cannot be extrapolated to operating conditions in distillation units. 7 p. application/pdf eng © Copyright 2022 The Authors, IOP Publishing https://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://iopscience.iop.org/article/10.1088/1742-6596/2118/1/012013/pdf Evaluation of mineral oils as matrices for AISI/SAE–1020 steel naphthenic corrosion study Documento de Conferencia http://purl.org/coar/resource_type/c_18co info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Text https://purl.org/redcol/resource_type/EC Reino Unido G R Conde-Rodríguez et al 2021 J.
