Their average range in
crude oil is C5H12 to C18H38 along with heteroatom-containing, oxygen, nitrogen
and sulfur. In addition to the previous contents, petroleum oil contains trace
amounts of metals such as iron, nickel, copper and vanadium. The physical
properties, particularly specific gravity, of the crude oil play a big role in
the global petroleum trading. It is defined as the ratio of the mass of a given
volume of the oil at 15°C to the mass of an equal volume of pure water at the
same temperature. Read More>>>>>>>>>
