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 ...

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 ...

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). ...

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 ...

The impact of biodiesel policy over raw material acquisition: a study about Brazilian Biodiesel National Programme
The aim of this article is to highlight and discuss the impacts of National Programme for Production and Use of Biodiesel - PNPB. This programme has some unique characteristics such as the incentive to social inclusion and local development by family farmers inclusion as oilseeds suppliers of biodiesel production, in this sense this study focus on biodiesel producer acquisition of raw material ...

China biodiesel industry encourages foreign investments
On January 23, 2015, China's National Energy Administration issued a biodiesel industry development plan (available in Chinese) to improve the biodiesel sector. The plan encouraged the production of cleaner fuels as well as the use of renewable fuels by promoting foreign companies' participation in the industry; mergers, acquisitions, and restructuring of domestic biodiesel companies; and fuel ...

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 ...

EIA Issues Short-Term Energy Outlook Report
On July 11, 2017, the Energy Information Administration (EIA) issued its June Short-Term Energy Outlook (STEO). EIA considered EPA’s recent rulemakings on the 2017 RFS volume requirements and proposed 2018 RFS volume requirements when developing its STEO for 2017 and 2018. Biodiesel production averaged 101,000 barrels per day (b/d) in 2016, and, according to EIA, is expected to ...

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 ...

Development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils
The development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils as feedstock is presented. A biodiesel batch reactor was fabricated using locally sourced materials. Three different transesterification reactions were performed on the feedstocks using the fabricated reactor. The reaction temperature and time were varied for the fresh and ...

Process optimisation of base catalysed transesterification of Karanja oil for biodiesel production
Biodiesel has been receiving increasing attention due to its renewable nature, lower pollution potential and green house gas benefit compared to mineral diesel. There are numerous factors, which affect the yield of biodiesel in a transesterification process such as reaction temperature, molar ratio of alcohol to oil, catalyst concentration, stirring speed, reaction time, etc. These variables are ...

Top Products - Avoiding Explosions in the Chemical Industry With Nitrogen
High-Purity Raw Materials from the By-Products of Biodiesel Production Producing diesel from plant-based raw materials creates unwanted by-products. Glaconchemie takes such by-products off of biodiesel manufacturers’ hands and uses them to develop high-purity raw materials. Glaconchemie uses self-produced nitrogen to overlay the production steps during further processing. In Germany, ...

Anaerobic treatment of crude glycerol from biodiesel production
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

Optimum reaction time, performance and exhaust emissions of biodiesel produced by microwave irradiation
While transesterification is well established, there remain considerable inefficiencies in existing transesterification processes. In this study an alternative energy stimulant, ‘‘microwave irradiation’’ was used for the production of the alternative energy source, biodiesel. The optimum parametric conditions obtained from the conventional technique were applied using microwave irradiation in ...

EPA grants BRAG petition requesting partial CDR exemptions for biodiesel products
On January 16, 2015, the U.S. Environmental Protection Agency (EPA) granted a petition from the Biobased and Renewable Products Advocacy Group (BRAG®) to add "biodiesel" as a chemical category for partial reporting exemption at 40 C.F.R. Section 711.6(b)(2)(iv) under the Chemical Data Reporting (CDR) rule and will be proceeding with a direct final rule to be published later in January. The ...

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 ...

Biodiesel production from high FFA crude rice bran oil and investigation on its properties as CI engine fuel
This study is an attempt to convert high free fatty acid (FFA) crude rice bran oil (CRBO) into biodiesel and to evaluate whether the biodiesel obtained meets the biodiesel quality standards prescribed by ASTM D 6751-07b. CRBO was subjected to a two-step transesterification process using HCl and NaOH as acid and base catalyst respectively with a 15% v/v of methanol to oil ratio. This process ...
