Research ArticleOpen accessIn the keywordsComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Useful Life of Lubricants Using Analytical Hierarchy Process (AHP) and Vector Projection Approach (VPA)Surachai Bovornsethanant, Somchai WongwisesProblem statement: In general, engine oil is usually changed as defined by car or lubricant manufacturers, which is according to mileage. However, it was found from past researches that, at the predefined mileage or timeframe, most lubricant is still acceptably usable and efficient. Approach: This research aimed to calculate useful life of lubricant in order to reach its maximum usefulness. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,640 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Transporting System Model for Oil RefineryRazman Mat Tahar, Waleed K. AbduljabbarProblem statement: Oil refineries are widely used to store various liquids and gases. Petroleum products are in high demand. Oil companies have abundant resources of petroleum products in pipelines and storage tanks. Approach: Included are storage tanks at retail gasoline station, home heating oil tanks, lubricant storage at automotive service facilities, propane tanks in all sorts of application, and oil … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,870 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of a Refrigeration System Based on Nano-Refrigerants and Nano-LubricantsHudaElslam A. S. Mohamed, Unal Camdali, Metin ActasMost of studies reported that disperse nanoparticles into refrigerants and lubricating oils lead to improve a coefficient of performance, due to improvement of thermal physics properties of a pure fluid, which leads to reduced energy consumption. Using nanoparticles in a refrigeration system is associated with many difficulties such as the cost of preparing and obtaining a stable and homogeneous mixture … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 12 Aug 2021 · 7,164 accessesView PDF Cite
