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 ...

Experimental investigations on diethyl ether as fuel additive in biodiesel engine
In this work, biodiesel (methyl esters) is produced from unrefined rubber seed oil by two-step transesterification process. Biodiesel engines are prone to cold-starting problems in winter seasons and emit more nitrogen oxides. To overcome these problems, diethyl ether is used as a fuel additive for biodiesel. The lower percentage addition of diethyl ether with biodiesel improves the engine ...

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 ...

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 ...

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 ...

Future of diesel engines with biodiesel economy
Biofuel is a fuel from biological raw materials. Any animal or vegetable fat can become raw materials for production of the natural diesel practically. Biodiesel economy is really changed after technology was allowed to make fuel from algas, commercial crops, animal fats and even the fulfilled culinary oils can become the most widespread source of fats. This fuel is safe in production and use, it ...

Biodiesel Analysis With Portable Midinfrared Analyzers
Biodiesel sales in the U.S. increased from 75 million gallons in 2005 to 250 million gallons in 2006. As ol September 2007, 165 companies arc producing biodiesel and 85 plants are under construction- Along with this rapid growth in production is the iuviI to ensure quality product* Methods fur specifications offinished biodiesel fuels include ASTM D 6751, ON 14214, and DIN 51606. The rest ...

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 ...

Mid-infrared analysis of biodiesel
The biodiesel industry is growing rapidly. and so is the need for analysis 10 ensure quality product and keep biodiesel in good standing. Biodiesellhat has residual glycerin, glycer· ides, or inorganic salts from the production process can cause problems such as Iilter plugging and injector coking in a diesel engine. The biodiesel blend ralio also can affect cold weather performance, lax ...

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, ...

Biofuels effluent, does it exceed regulatory limits?
The US Environmental Protection Agency (EPA), as well as other regulatory agencies around the world, have established limitation guidelines for discharges of “oily wastes” from facilities utilizing any type of oil and grease in their manufacturing process. However, recently several biodiesel plants in the US have been fined for illegally discharging vegetable-based oil and grease and polluting ...
