A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Biofuels such as biodiesel and bioethanol have been studied and tested in many countries including India. One of the methods to reduce the use of fossil fuel is blending ethanol with fossil diesel. However, an emulsifier or a co-solvent is needed to homogenize the diesel-ethanol blends. The ric...

Biodiesel will play an increasing role in fulfilling the world’s energy requirement. The world has experienced negative effect from the fossil fuel such as global warming and acid rain etc. With the increase in consumption of biodiesel, its impact on environment has raised a discussion around the world. Energy requirement of the world will increase in coming future and is projected to increase ...

The present study aims to compare the efficiency of a single extraction and a 3-stage cross-current extraction of PAHs from both lowly contaminated (LC) and highly contaminated (HC) sands using palm kernel and soybean oils (PKO, SO). It is observed that 3-stage cross-current extractions increase the total efficiencies compared to single extractions by 18.7–22.7% and 27.2–30.6% for LC and HC san...

Oil from brebra (Millettia ferruginea) is the potential raw material for biodiesel production. The refining of crude oil requires a series of purification steps to produce quality biodiesel. The objective of the study was to produce refined oil from brebra seed for biodiesel production. Crude oil extraction was carried out using mechanical press and solvent extraction methods. Impurities of the...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

Fuel return valve is an important part of aviation engines. It achieves the cooling of integrated drive generator by regulating the amount of fuel in the oil cooler of integrated drive generator. Fault modeling and simulation of fuel return valve can provide targeted guidance for its maintenance. This paper establishes fuel return valve's mathematical model which includes the flow control valve...
