Research ArticleOpen accessIn the abstractLab-on-Chip Methodology in the Energy Industry: Wettability Patterns and Their Impact on Fluid Displacement in Oil Reservoir ModelsMarc H. Schneider, Patrick TabelingProblem statement: We present an experimental study of multiphase transport in porous media with controlled wettability patterns based on lab-on-chip methodology. Approach: Fractional, or patterned, wettability is known to have an enormous impact in the petroleum industry on oil recovery and continuous efforts are being made to assess the role of such conditions. Results: Thus far, due to the absence … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,880 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransesterification of Palm Oil for the Production of BiodieselKhalizani Khalid, Khalisanni KhalidProblem statement: Palm oil is known as an important source of edible oil with significant values of renewable energy. Depletion of petroleum had captured much attention on producing biodiesel from the palm oil. Approach: The most concerning methods for the production of biodiesel were discussed, namely transesterification (alkali and acid), enzymetic approach and supercritical alcohol. Results: The results showed the … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrowave Assisted Bioethanol Production from Sago Starch by Co-Culturing of Ragi Tapai and Saccharomyces CerevisiaeN. Saifuddin, Refal HussainProblem statement: Environmental issues such as global warming and recent events throughout the world, including the shortage of petroleum crude oil, the sharp increase in the cost of oil and the political instability of some crude oil producing countries, have demonstrated the vulnerability of the present sources for liquid fuel. These situations have created great demand for ethanol from fermentation … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Performance and Emission Characteristics of Low Heat Rejection Diesel Engine with Ethanol as FuelP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: Depleting petroleum reserves on the earth and increasing concerns about the environment leads to the question for fuels which are eco-friendly safer for human beings. The objective of present work was to investigate the effect of coating on piston, cylinder head and valves of a Diesel engine on the performance and emission characteristics of exhaust gases using wet … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,219 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-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 PDFCite
Research ArticleOpen accessIn the abstractFully Integrated Hydrocarbon Reservoir Studies: Myth or Reality?Christoforos Benetatos, Dario VibertiProblem statement: In the petroleum industry and especially during reservoir studies, data coming from different disciplines must be combined in order to generate a model that is representative of the reservoir being studied and can be used for defining the most viable development strategy of the field from both an economic and technical standpoint. Each of these disciplines represents an … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 9,975 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlkali Pretreatment and Enzymatic Hydrolysis of Cattails from Constructed WetlandsBo Zhang, Abolghasem Shahbazi, Lijun Wang et al.Problem statement: To date, production of liquid fuel, particularly ethanol, has only been economically feasible from food crops that are high in sugar and starch. However, the use of arable land for fuel rather than for food production and the use of a food source for fuel rather than as food have created issues in prices and availability of traditional … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 9,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Seven-Lump Kinetic Model in the Fluid Catalytic Cracking UnitMehran Heydari, Habib AleEbrahim, Bahram DabirProblem statement: The effective simulation of the Fluid Catalytic Cracking (FCC) operation requires a good understanding of many factors such as, reaction kinetic, fluid dynamics and feed and catalyst effects. Approach: In this model the reactor has been considered as an isothermal riser. The reactions in the riser occur with the fluid and the solids in ideal plug flow. Because … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction of Oil from Jatropha Seeds-Optimization and KineticsSepidar Sayyar, Zurina Zainal Abidin, Robiah Yunus, Azhari MuhammadProblem statement: Jatropha curcas is a wonder plant with a variety of applications and enormous economic potentials. Oil from the seeds can be used as alternative fuel and for making biodiesel which aims to overcome energy crisis problems. In this study, extraction of Jatropha oil from seeds was optimized using organic solvent based on the amount of the extracted oil. … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 13,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multicultural Comparison of Engineering Students: Implications to Teaching and LearningZaki Shkair Seddigi, Luiz Fernando Capretz, David HouseProblem statement: Personality considerations have become increasingly important in recent years, but studies involving the personality characteristics of engineers have been scarcely reported. Engineers today are expected to have a broader range of skills than in the recent past because users are now equally concerned with the technical as well as the personal services provided by engineers. Approach: A multicultural … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,315 accessesView PDFCite
