More information on crude oil
Crude oil is a fossil fuel natural origin. It is unrefined petroleum product consisting of hydrocarbon deposits; when crude oil is refined, it is transformed into major energy sources used to facilitate global industrial activity and also for use at national level. Crude oil and natural gas are called hydrocarbons because they are both of carbon and hydrogen compounds. crude oil molecules contain five carbon atoms per molecule. Natural gas molecules are usually shorter; or four or less carbon. A barrel of oil contains oil of 39% fuel (used for power generation, ships bunkers, bitumen for road construction and processing into gasoline and diesel), 28% denaphta, (a product petrochemical used for various applications, including blending in gasoline), 24% diesel (used in the production of electricity, diesel for transport between other industrial uses); 7% jet fuel and kerosene (used as fuel for aviation and heating / lacuisson respectively) and 2% (LPG used for cooking and heating). refining of crude oil begins the process of simple distillation but progress in other processes more sophisticated; using complex equipment to separate the tens of hydrocarbon compounds in crude oil into individual chemical units and transform these chemical units in various end products that the demands of global energy markets.
Crude oil is classified as light, medium or heavy according to its measured API gravity (standards developed by the American Petroleum Institute). API gravity is a petroleum fluid measuring light or heavy way is compared to water. If its API gravity is greater than 10, it is lighter and floats on water if it is below 10, it is heavier and sinks. Most values are between 10 and 70 degrees API gravity.
- Light crude oil has a higher API gravity 31.1 O API
- Medium crude oil has an API gravity between 22.3 and 31.1 0 0 API API
- Heavy crude oil has an API gravity below – below 22.3 0 API
Crude acid has a higher hydrogen sulfide content of 1%. It also contains carbon dioxide. It is usually transformed into heavy oil such as diesel instead of gasoline to reduce the cost of treatment. crude oil contains less than 0.5% sulfur and contains only traces of hydrogen sulfide and carbon dioxide. crude is most commonly used for fuel conversion.
