The Effect of Biodiesel Feedstocks on InnfraRed Blend Measurements
What is the effect of biodiesel feedstocks on measurement accuracy? This common question coming from individuals measuring the percent biodiesel in diesel leads to several other questions before the answer is complete. How does infrared measure biodiesel content? Fortunately for manufacturers of infrared instrumentation, biodiesel has a unique signature from diesel in the infrared range of the ...

The Effect of Feedstocks on InfraRed Blend Measurements
IR can be a simple, effective way to measure biodiesel blend ratios from a variety of feedstocks BY SANDRA RINTOUL With biodiesel hitting a new production record of 823 million gallons through October and expected to reach 1.28 billion by 2013, more biodiesel will ultimately be blended into our diesel fuel. This boom in production has opened the doors to a number of potential biodiesel ...

European biodiesel market and rapeseed oil: what impact on agricultural food prices?
The last decade has seen a rapid increase in the production and consumption of biodiesel in the EU. This development has been especially stimulated by EU policy as a means to promote energy security and to reduce the emissions of greenhouse gases. However, in recent years, biodiesel production has been questioned due to the possible impact on food prices. This paper aims to explore the impact of ...

A Fully Integrated Process for Biodiesel Production from Microalgae in Saline Water
This project will demonstrate the technical and economic feasibility of an integrated process for the production of microalgal oils that are suitable as a feedstock for biodiesel production. A preliminary economic feasibility study and assessment of total greenhouse gas emissions (GHG) would be carried out based on the results of small-scale studies and, if successful, would be followed by a ...

Assessment of the EU target on renewable energy for transport in the framework of the European vegetable oil sector
Biofuels is currently driving the interest in bioenergy sector. The recently issued Renewable Energy Directive (2009/28/EC) confirms the 10% target, set by the EC, for energy from renewable sources in transport. The European Union is the largest producer of biodiesel in the world and biodiesel is also the most important biofuel used in the EU. The aim of this paper is to investigate the biomass ...

Water-saving analysis on an effective water reuse system in biodiesel feedstock production based on
Chlorella zofingiensis fed-batch cultivationThe micralgae-based biofuel obtained from dairy wastewater (DWW) is considered a promising source of energy. However, this process consumes water due to the concentration of wastewater being normally too high for some micoralgae cultivation, and dilution is always needed. In this work, the cultivation of microalgae has been examined in non-recirculated water (NR) and recirculated water systems ...

Landfill gas, canola and biodiesel: working towards a sustainable system
Snohomish County in western Washington State began converting its vehicle fleet to a blend of biodiesel in 2005. As prices for biodiesel rose due to increased demand for this cleaner-burning fuel, Snohomish County looked to its farmers to “grow” this fuel locally. Suitable oil seed crops for biodiesel feedstock include canola, mustard and camelina. The residue, or meal, has high value ...

Meeting the Challenges of Biodiesel Blend Measurements with Portable Mid-Infrared Analyzers - Case study
In a published paper on biodiesel blend quality submitted by the National Renewable Energy Laboratory1, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For fleet managers, an incorrect blend can mean a total shutdown of operations. On the ...

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, ...

New Feedstock Options and Trends Boost Biodiesel Production
Special to The Digest In the United States, efforts to replace fossil fuels with biofuels are gaining momentum, supported by growing public awareness, government programs and emerging waste-to-fuel technologies. The Environmental Protection Agency’s (EPA) analysis of the Renewable Fuel Standard (RFS) projected that several types of biofuels, such as biodiesel, could yield lower ...

A New way to Skim and Save – Reprinted from Biodiesel magazine - Case study
Oil and water don’t mix; efficiency and profits often do. While the oil and water adage is well known to biodiesel producers — it means feedstock is contaminated with water — it also offers an opportunity. Biodiesel plant personnel are always looking for new tools and equipment that help a facility operate more ...

Parametric study of biodiesel quality and yield using a bench-top processor
Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

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 ...
