Not all crude oil is the same. The composition varies according to the oil reserve from which it is extracted. Refinery output for different crude oils. API stands for the American Petroleum Institute. API gravity is a measure of the density of the crude oil. A higher API gravity indicates less dense oil. Look at the charts and the illustration of fractional distillation. Explain which crude oil is best suited to the production of gasoline.

Gasoline is a fuel made from crude oil and other petroleum liquids. It is a volatile liquid with a low boiling point. It is considered as one of the light products. Saharan crude oil from Algeria has the highest proportion of light products, and is best suited for the production of gasoline.

Not all crude oil is the same. The composition varies according to the oil reserve from which it is extracted. Refinery output for different crude oils. API stands for the American Petroleum Institute. API gravity is a measure of the density of the crude oil. A higher API gravity indicates less dense oil. Explain why crude oil from Venezuela is called heavy oil. How does the molecular mass of the most common hydrocarbon in this crude oil differ from the hydrocarbons commonly found in Saharan crude oil?

The crude oil from Venezuela is called heavy oil because it has a high percentage of long carbon chain hydrocarbons. The majority of products made from this crude oil such as bitumen, lubricating oils and fuel oils will have a high density or molecular mass compared to those in Saharan crude oil.

Not all crude oil is the same. The composition varies according to the oil reserve from which it is extracted. Refinery output for different crude oils. API stands for the American Petroleum Institute. API gravity is a measure of the density of the crude oil. A higher API gravity indicates less dense oil. The terms sweet crude oil and sour crude oil refer to the sulphur content of the crude oil. Crude oil with less than 0 . 5 % sulphur content is classified as sweet. Which crude oils on this graph are considered sweet oil?

Saharan (Algeria) and Brent (North Sea) are classified as being sweet crude oil. This is because, both of them have a sulphur content less than 0 . 5 % . That is, 0 . 2 % of sulphur in Saharan and 0 . 3 % of sulphur in Brent. Sweet crude oil is considered a valuable and efficient source of crude oil due to the fact that sulphur lowers the yield of various refined petroleum products such as gasoline, diesel fuel, and even plastics.
