biodiesel production method Articles

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Putting the brakes on biodiesel

      Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state’s largest markets. The problem, they say, lies with the fuel’s nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas’ eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently ...

  • Value stream mapping based on energy and cost system for biodiesel production

    Organisations have to give more attention to customer demands for survival and also for increasing their market shares. But customers' demands are not stable. The main problem of all organisations is how to cut costs during production process. The solution to this problem is built up with lean–based production systems. Value stream mapping identifies those areas where unwanted productivity is ...

  • 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 ...

  • 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 ...

  • Perfect products for fuel consumption

    In present time fuel customers get offered a row of perfect products for fuel consumption enhancement, processes of combustion, both in petrol engines for cars, and to the diesel. All additives to petroleum are harmless to the car and serve as protection against the low-quality fuel which has got to a tank and will increase saving. They will secure and will burn any petroleum and if fuel is a ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • The impact of blending techniques, feedstock choice, and analytical techniques on biodiesel blend accuracy

    The National Renewable Energy Laboratory in Golden, Colorado, USA, conducted a nationwide study released in 2005 that compared the actual content of biodiesel in biodiesel/ petroleum diesel blends vs. the nominal content. Results showed that 36% of the samples were incorrectly labeled. Inaccurately blended biofuels can have a negative impact throughout the supply chain, affecting distributors, ...
