The present-day oil refining market has the potential to process opportunity crudes. The degree of corrosion and fouling issues has increased in terms of processing opportunity crudes. In the case of changing crude slates, predicting the impacts of crude oil on production is necessary to ensure safe and profitable processing. Crude oil can be characterized by the quantitative and qualitative analyses of saturates, aromatics, resins, asphaltenes and contaminants as well as the determination of its physical and chemical properties. The complementary nature of these analyses is necessary to identify the root causes of fouling and corrosion problems and quantify the impact of them. In this study, analytical methods were developed to investigate the effect of crude oils on production in terms of fouling and corrosion, which can be used to characterize crude oil from different sources. The compatibility, emulsification tendency and fouling potential of crude oil were analyzed by the developed analytical methods. The measurement method to assess the compatibility of crude oils is based on the determination of the flocculation tendency of asphaltenes in oils. A Porla GLX Step Analyzer was used for the compatibility tests. Emulsification and fouling tendencies were measured by our in-house designed laboratory equipment. These measurements were conducted under typical operating conditions. The developed analytical methods were validated by crude oils from five different sources.

“…This phenomenon concerns most industrial sectors, notably the aeronautics industry, the automotive industry and the chemical and petrochemical industries 18 in which the economic stakes are therefore considerable. Corrosion is not only a source of wastage of raw materials and energy but can also cause serious accidents and therefore contributes to environmental pollution 19 .…”

We began, in this work, by the synthesis of the Cu(II) complex with DL-a-alanine which is characterized by powder X-ray diffraction, the UV-visible spectroscopy and the infrared spectroscopy. The RXs show that the complex has the formula C 6 H 12 N 2 O 4 Cu, 2H 2 O while the experimental data show that the ligand is bidentate and the studied complex adopts octahedral stereochemistry. We then studied the inhibitory effect of Bis (DL-a-alaninato) copper dihydrate complex on ordinary steel in 1M HCl solution. The corrosion inhibition study of this complex was carried out by the electrochemical method (stationary and transient). The measurements carried out by this method gave a maximum efficiency of 88% to 10 -5 M of Bis (DL-a-alaninato) copper dihydrate complex on an ordinary steel surface of 1 to 2 cm dimension in the presence of a 1M HCl solution. The obtained results show that the adsorption process of the Bis (DL-a-alaninato) copper dihydrate complex on the metal surface obeys the Langmuir adsorption isotherm.

“…The changing world supply of crude oil towards properties of higher density, higher sulfur concentration, and higher acidity can result in additional fuel production challenges for oil refineries [1,2]. One such production challenge is an increased risk of naphthenic acid corrosion that can result in various surface degradation profiles of uniform corrosion, non-uniform corrosion, and localized pitting in piping systems at temperatures between 150°C and 400°C [3,4].…”

Abstract. The accuracy, precision, and reliability of ultrasonic thickness structural health monitoring systems are discussed in-cluding the influence of systematic and environmental factors. To quantify some of these factors, a compression wave ultrasonic thickness structural health monitoring experiment is conducted on a flat calibration block at ambient temperature with forty four thin-film sol-gel transducers and various time-of-flight thickness calculation methods. As an initial calibration, the voltage response signals from each sensor are used to determine the common material velocity as well as the signal offset unique to each calculation method. Next, the measurement precision of the thickness error of each method is determined with a proposed weighted censored relative maximum likelihood analysis technique incorporating the propagation of asymmetric measurement uncertainty. The results are presented as upper and lower confidence limits analogous to the a 90/95 terminology used in industry recognized Probability-of-Detection assessments. Future work is proposed to apply the statistical analysis technique to quantify measurement precision of various thickness calculation methods under different environmental conditions such as high temperature, rough back-wall surface, and system degradation with an intended application to monitor naphthenic acid corrosion in oil refineries.
