North Dakota recently required producers to extract some of these gases, which include propane and butane. The state is the epicenter of the new oil boom and was the departure point for most of the more than 400,000 oil tank cars that rolled across the United States in 2013. 4. But the...
PROCEDURE 1: Crude Oil Sample Preparation Depending on crude type and composition, it may be hard to obtain a stable homogenous sample. Viscous or asphaltene and bitumen containing crudes are particularly difficult to extract. The addition of toluene or x...

The method of the present invention comprises: a washing and dehydrating step of removing contaminants and bacteria of a processed plant selected to perform evaporation extract so as to extract phytochemical from the process plant; a preparing step of crushing or pulverizing the plant into a size ...
The manufacture of polyester, which is used to make twill nearly as frequently as cotton, is inherently bad for the environment. This fabric is made from petroleum, which is a non-renewable resource, and a number of toxic chemicals are used to extract usable polymers from this "fossil fuel"...
Canada has 171 billion barrels within its borders. However, nearly all of these reserves are located in Alberta's "sandpits," a terrain that makes the oil and gas harder to extract from the earth than it is in other countries. However, technological innovations are expected to make extractin...
find themselves to be commercially viable targets. For example, increased oil costs helped encourage the development of the techniques now known as hydraulic fracturing, which involves using steam, gas, and chemical injections to break up rock formations and extract the hydrocarbons contained within ...
(SAGD), which is a secondary recovery technique used to extractheavy crude oilthat is buried too deep or otherwise too burdensome to access with primary methods. Also known as the steam flooding process, SAGD uses steam generators to produce highly pressured steam that travels through pipelines ...
Petroleum companies are divided intoupstream, midstream, and downstream, depending on the oil and gas company's position in the supply chain. Upstream oil and gas companies identify, extract, or produce raw materials. Downstream oil companies engage in the post-production of crude oil and natural ...
