Abstract:

Isolation of naphthenic acid from model oil using hydroxide based ionic liquid was investigated. A detailed de-acidification study at different temperatures and different ionic liquid/model oil was performed and the content of naphthenic acid before and after extraction was calculated. The ILs containing hydroxide anions has the potential to completely deacidify model oil having high TAN with extremely low ionic liquid /oil ratio.

Abstract:

Naphthenic acids are among the water, oil and soil contaminants mostly by accident. The review was carried out to examine the types and sources of Naphthenic acids. The toxic nature of naphthenic acids is mostly attributed to their surface characteristics due to the presence of a hydrophobia alkyl group and hydrophilic carboxylic group in their salts. Different method based on the use of different test organism like bacteria, aspen, fish, zooplankton and rat have been used by researchers to measure the level of toxicity of naphthenic acid in substances. Naphthenic acid caused corrosion in the

Abstract:

ABSTRACT The relationship between structural composition of rubber oil and anti-yellowing performance of oil-extended polystyrene-block-polybutadiene-block-polystyrene triblock copolymer (SBS) was studied in this work. The experimental results proved that anti-yellowing of oil-extended SBS was determined by the rubber oil and was irrelevant with SBS. The anti-yellowing performance of the SBS filled with paraffinic-based rubber oil was better than that of the SBS filled with naphthenic-based rubber oil. In addition to the partially hydrogenated aromatic hydrocarbons in rubber oil, heavy naphthe

Abstract:

To withstand harsh conditions and have a moderate strength, it is desirable to use natural rubber for base isolators. In addition, previous studies have measured the magnetorheological (MR) effect under low-strain range, mostly within 10%. In the reality, it is necessary to evaluate the performance under large-strain range for base isolators. In this study, material properties of natural rubber-based MREs with various mixing ratios were evaluated under large-strain range (~100%). In the first step, MREs with various iron ratios were fabricated and evaluated to observe the MR effect according t

ABSTRACT The chemical composition and physical properties of a crude oil determine the behavior of the oil and the way its properties will change when the oil is spilled at sea. Reliable knowledge of the oil's behavior will enable the most effective countermeasure techniques to be used in a spill situation. A diverse range of crude oils is coming into production in the North Sea. The weathering behavior and chemical dispersibility of three very different crude oils—Troll (naphthenic), Balder (asphaltenic), and Nome (waxy)—have recently been thoroughly investigated through bench- and meso-scale

Traction measurements for two kinds of synthetic naphthenic traction oils were carried out, using a two-roller machine. The Eyring stress and shear modulus of test oils were estimated simultaneously by a curve-fitting procedure based on the nonlinear viscoelastic model introduced by Johnson and Tevaarwerk. As a consequence, it has been found that the Eyring stress decreases with an increase in contact pressure, and it increases with oil temperature. It has been also clarified that the effective shear modulus, including the effect of the roller compliance, decreases with an increase in contact

Abstract:

Abstract Naphthenic acids (NAs) have been implicated as some of the most toxic substances in oil sands leachates and identified as priority substances impacting on aquatic environments. As a group of compounds, NAs are not well characterized and comprise a large group of saturated aliphatic and alicyclic carboxylic acids found in hydrocarbon deposits (petroleum, oil sands bitumen, and crude oils). Described is an analytical method using negative-ion electrospray ionization mass spectrometry (ES/MS) of extracts. Preconcentration was achieved by using a solid-phase extraction procedure utilizing

Abstract:

This paper summarizes the results of various attempts to implement a neural network for solving corrosion problems. The first activity was aimed to develop a model able to predict crevice corrosion of stainless steel and related alloys in chloride containing media from long-term exposure tests. Second, the preliminary evaluation of a neural network approach for rapid prediction of naphthenic acid corrosion performance (NAC) of carbon and stainless steels in a crude oil distillation unit will be described. In this work, the neural network was trained on the basis of experimental data from labor
