aPetroleum (also called crude oil), in the unrefined or crude form, like many industrial feedstocks has little or no direct use and its value as an industrial commodity is only realized after the production of salable products. Even then, the market demand dictates the type of products tha...
Oil is often called “black gold,” yet crude oil has a range of viscosity and can vary in color from black to yellow depending on its hydrocarbon composition.13Distillation, the process by which oil is heated and separated into different components, is the first stage in refining. Crude Oil...

California is the nation's fourth largest producer of crude oil and has the third largest oil refining industry (behind Texas and Louisiana). Because crude oil is a globally traded commodity, natural and geopolitical events can affect its price. These fluctuations affect state revenues because a ...

The transesterification process is also known as simply alcoholysis because the vegetable oil is made to react with alcohol [53]. The most frequently used alcohols are ethanol and methanol as these are easily and cheaply available. The process converts the triglycerides into esters in the presence...
Brent, next to West Texas Intermediate (WTI), is one of the lightest crude oils. With a low content of sulfur, it is ranged among the so-called sweet crude oils. Most of the Brent crude oil is refined into gasoline and middle distillates in Northwest Europe. Benchmark oil prices Other...
CRUDE OIL Commonly Used Chemical Sub-classifications in the Petroleum Industry: • Olefinic: linear chain aliphatic hydrocarbons with double or triple bonds; ethylene (C 2 H 2 ) is the smallest olefin. • Paraffinic: (paraffins, C n
Bitumen is a substance produced through the distillation of crude oil that is known for its waterproofing and adhesive properties.
Combining these elements together, we can see that the most desirable type of crude oil is light sweet crude. This is because it is highly efficient, leaving minimal residue in its refinement process while also being easy to distill and transport due to its low density. ...
