  • Graphical exergy analysis of reactive distillation column for biodiesel production

    This paper brings the novelty of the exergy analysis technique using Ex–N–A diagram to a packed reactive distillation (RD) column for biodiesel production. In this study, biodiesel is produced through the esterification of fatty acid with methanol. The simulation of the column was performed based on the non–equilibrium (NEQ) model of a three–phase packed RD system. The graphical Ex–N–A method was ...

  • Energy analysis and potentials of biodiesel production from Jatropha Curcas in Tunisia

    Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and widely grown in South and Central America, Africa, and Asia (Achten et al., 2007; Kumar et al., 2011). ...

  • Microtox aquatic toxicity of petrodiesel and biodiesel blends: The role of biodiesel's autoxidation products

    The authors investigated the acute Microtox toxicity of the water accommodated fraction (WAF) of six commercial soybean biodiesel/petrodiesel blends at different oil loads. We analyzed five fatty acid methyl esters (FAMEs), C10–C24 n‐alkanes, four aromatics, methanol, and total organic carbon (TOC) content. At high oil loads, the WAFs' toxicity was significantly higher for blends containing ...

  • Performance analysis of a single cylinder DI diesel engine using different biodiesel

    Biodiesel produced from cottonseed oil is quite a promising alternative fuel for diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity and carbon residue. But the performance of vegetable oils can be improved by modifying them through the transesterification process. The research work discusses the ...

  • GHG balance of biodiesel production and consumption in EU

    The promotion of biofuels as energy for transportation in the industrialised countries is mainly driven by the perspective of oil depletion, concerns about energy security and global warming. Nevertheless, the production of biofuels entails emissions to the environment coming from the different stages in the product life cycle. This paper evaluates the environmental impact of pure rapeseed ...

  • Sustainability assessment of microalgal biodiesel production processes: an exergetic analysis approach with Aspen Plus

    Biodiesel production growth rate keeps increasing every year with the hope of replacing fossil based liquid fuel which is near exhaustion. Energy efficiency methods coupled with environmental and economic sustainabilities would render biodiesel production attractive. Algal cultivation and oil extraction processes are found to be energy intensive hence exergy destructive. This study presents the ...

  • Exergetic cost analysis and sustainability assessment of an Internal Combustion Engine

    This study deals with exergy cost analysis and sustainability assessment of a diesel engine, which runs with diesel no. 2 and two different biodiesel fuels at 1400 1/min test speed. Maximum total cost per exergy flow input rate and total exergy cost are found to be 12.5549 $/kW•year and 1728.312 $/year for one of the biodiesel fuels, respectively, while minimum values of these costs are ...

  • Exergy analysis of engines fuelled with biodiesel from high oleic soybeans based on experimental values

    This study dealt with energy and exergy analyses of a John Deere 4045T diesel engine run with no. 2 diesel fuel, Soybean oil Methyl Ester (SME) and High-Oleic soybean oil Methyl Ester (HOME) at 1400 1/min. It was aimed at determining energy and exergy efficiencies, energy losses and exergy destructions of the combustion process and comparing exergetically the fuels used. The specific exergy of ...

  • Biodiesel fuel for transportation: Status and issues in the United States

    The United States consumed 3.39 billion barrels of gasoline, 1.54 billion barrels of diesel fuel, and 0.59 billion barrels of jet fuel in 2007. And it currently imports 3.66 billion barrels of oil and petroleum products per year, 65% of US consumption, compared to 1.71 billion barrels (or 36%) 20 years ago. To address the growing gap between petroleum consumption and domestic production, the US ...

  • Comparison of EN 14078 and ASTM D7371 infrared biodiesel methods

    Infrared (IR) analysis is the most widely used measurement technology for measuring biodiesel in diesel. Both EN 14078 and ASTM D7371 methods use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectroscopy. Infrared is a common spectroscopic technique used for quantitative and qualitative analysis. In the biodiesel measurement, the fatty acid methyl ...

  • Energy and exergy analyses of a CI engine fuelled with palm biodiesel based on experimental data

    Only energy analysis is not enough to define the best efficiencies of any system, so exergy analysis uses to understand and improve the actual efficiencies of the whole system. Energy analysis identified the energy losses but could neither identify the irreversible losses nor their location. These are, however, could be clearly explained with the application of exergy analysis. In this study both ...
