A unified perspective on the phase behaviour of petroleum fluids
We present a coherent and unified group of general explanations for the various phase transitions, which may occur in the seven naturally occurring petroleum fluids with emphasis on their heavy organics. The seven petroleum fluids include, in the order of their fluidity, natural gas, near-critical gas-condensate, light crude, intermediate crude, heavy oil, tar sand and oil shale. At first the ...

Dilemmas and solutions for a sustainable green transition
Mitigation of global warming and transitioning to a green and sustainable world are counteracted by a number of barriers and dilemmas. The paper analyses a number of these barriers and dilemmas in order to highlight efficient strategies and solutions for a sustainable development. Most governments in industrial countries do not pay enough attention to concepts as limits to growth in a finite ...

Can low oil prices be good for the environment?
Deepwater drilling rigs are sitting idle. Fracking plans are being scaled back. Enormous new projects to squeeze oil out of the tar sands of Canada are being shelved. Maybe low oil prices aren't so bad for the environment after all. The global price of oil has plummeted 31 percent in just five months, a steep and surprising drop after a four-year period of prices near or above $100 a barrel. ...

Falling Gasoline Use Means United States Can Just Say No to New Pipelines and Food-to-Fuel
Freeing America from its dependence on oil from unstable parts of the world is an admirable goal, but many of the proposed solutions—including the push for more home-grown biofuels and for the construction of the new Keystone XL pipeline to transport Canadian tar sands oil to refineries on the U.S. Gulf Coast—are harmful and simply unnecessary. Gasoline use in the United States is ...

Will we ever stop using fossil fuels?
Not without a carbon tax, suggests a study by an MIT economist. In recent years, proponents of clean energy have taken heart in the falling prices of solar and wind power, hoping they will drive an energy revolution. But a new study co-authored by an MIT professor suggests otherwise: Technology-driven cost reductions in fossil fuels will lead us to continue using all the oil, gas, and coal we ...

Abrasives 98% purity Green Black silicon carbide abrasive powder F12- F240 SIC carborundum Grit
Silicon carbide (SiC) is made from quartz sand and petroleum coke or coal tar, wood chips and other raw materials by smelting in high temperature electric resistance furnace . In the high technology non-oxide refractory raw materials , such as C, N, B ,ilicon carbide is the most widely used and one of the most economic material. It can be called corundum or refractory sand. It is brittle and ...
