1. crude oil is a complex mixture of hydrocarbons with small amts of impurities. So in terms of elements, crude oil consist of Carbon and Hydrogen as the main components as well as traces of impurities such as sulphur, nitrogen ad oxygen containing compounds.
Particularly in terms of chemistry, which is your chosen topic, to separate is to extract or isolate.
Crude oil is a very complex mixture of hydrocarbon compounds with some inorganic compounds. Simple quality terms (light/ heavy and sour/ sweet) are defined for convenience and are inadequate terms to fully characterize the crude. However, as discussed in the links, a crude that has less than 0.5% sulfur content is sweet crude. Oil that is between 37 to 42 degrees API in density is light oil. Other definitions exist (see link), however this appears the range used for US produced crude. Light sweet crude will sell for higher prices than other grades, (Heavy sour, heavy sweet, light sour). Many countries produce light sweet crude including Russia, Saudi Arabia, Iraq, Brazil, Angola, Nigeria, and the US. Please see related links.
