Investigation of fatty acid methyl esters in jet fuel
Sustainable aviation fuels research has considerable momentum in efforts lead by government, academia and industry. Environmentally sound domestic fuels allow significant benefits, while also creating some challenges due to their novelty. One of these challenges is the cross contamination of fatty acid methyl esters (FAME) in biodiesel with jet fuels. It was suspected that sharing the same supply ...

Performance of a direct diesel engine using aviation fuels blended with biodiesel
In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four–cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break ...

Exergetic and exergo–economic analysis of a turboprop engine: a case study for CT7–9C
The turboprop engine has played an important role in short haul commuter and military transport aircraft where high speed is not critical. It may provide the aviation sector with one of the most significant means of achieving reduced operating costs through reductions in fuel consumption. This paper deals with exergo–economic analysis of a modern turboprop engine (CT7–9C) with a free power ...

Advocates of Renewable Energy: Be Careful What We Promise
Sixty years ago, nuclear was hyped as a source of energy / electricity that would be “too cheap to meter.” The OPEC oil embargo dashed the western world's dream of bountiful low-cost energy but, when Brian Mulroney was elected a decade later, he terminated Canada's research into renewables because “the energy crisis was over.”That funding cut led to my appointment as head of the Solar Energy ...

Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

CITGO Is Worth Protecting
In the last ten years the fracking revolution has led to amazing growth and vastly increased energy security for the United States. We’ve gone from the number-one refined product importer in the world to the number-one exporter. Workers in American refineries are fueling the country and, increasingly, the world. More than one hundred high-tech U.S. refineries support millions of jobs, ...

Meeting the challenges of biodiesel blend measurements
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 ...

Airbus CEO talks about emissions, innovation and more
These are heady times for the commercial-aircraft business at Airbus and Boeing, as airlines place huge orders for new planes. Each is working on more fuel-efficient aircraft to satisfy airlines that want lower fuel bills and regulators who want lower emissions from aircraft. Airbus Group CEO Tom Enders spoke last month to an aviation conference in Dallas and urged the industry to put more ...

Pollution reduction from flares by swirl vanes in a cross-flow
The effect of swirl on the performance of a flare stack was experimentally investigated as a passive control technique for combustion in a cross-flow. The burner comprised a circular fuel nozzle with a co-annular airflow, swirled by a concentric vane swirler, with a crosswind of air at the flare tip. It was found that the flames issuing from swirl-vane flare tip were shorter and had wider flame ...

Octane Testing-Gasoline from Gas
Octane engine is used for gasoline octane testing. Gas to Gasoline or Gas-to-Liquids, it is a more economical and cleaner way to convert natural gas into gasoline and other liquid fuels. Several steps are needed to turn natural gas into gasoline. Natural gas is broken down under high temperatures into acetylene and a liquid-phase step converts the acetylene into ethylene. This can be converted ...

Year One – A review of British Columbia’s carbon tax
On July 1, 2008 British Columbians saw gas prices rise by 2.34 cents per litre and on July 1, 2009 gas prices increased again by an additional 1.17 cents. This is a result of the carbon tax introduced by the B.C. government in July of 2008 as part of its Climate Action Plan. The Climate Action Plan commits the Province to a 33% reduction of greenhouse gas ('GHG') emissions by 2020. B.C.'s carbon ...

Why Does A City Need A Pyrolysis Machine Converting Tire To Oil
The quantity of waste that humans create each and every day is completely staggering currently. The most significant problem with modern waste is the fact a lot of it really is non-biodegradable, and several may take over one thousand years to finally decompose. It is a huge problem for cities around the globe which are literally buried in garbage and waste. However, there is now an ...

Why airlines keep pushing biofuels: They have no choice
The number of global fliers is expected to more than double in the next two decades. In order to carry all those extra passengers, airlines are turning to a technology very few can make work on a large scale: converting trash into fuel. They have no other choice. As people in countries such as China, India and Indonesia get wealthier they are increasingly turning to air travel for vacation or ...
