What’s the differences between the light crude oil and heavy crude oil?
1, light crude oil and heavy crude oil is different in the density of crude oil. Crude oil relative density is 0.9 to 1.0, known as heavy crude oil; relative density is less than 0.9, is called light crude oil.
2, API Gravity (American Petroleum Association proportion) is also another indicator to tell them apart. API Gravity greater than 31.1, belonging to light crude oil; API Gravity less than 22.3, belonging to heavy crude oil.
3, heavy crude oil has more high-fried cut fraction, that is, more "impurities", the mining and refining process and technology is more complex; the "impurities" in the light crude oil is relatively small, mining and refining process and technology Relatively not so complicated.
4, in the refining process, the same volume of crude oil, light crude oil can produce more high-value products (such as LPG, aviation gasoline, gasoline, diesel, kerosene, etc.); and heavy crude oil can be extracted High value products are relatively small, a large part of crude oil in the end have become a "dross" (such as paraffin, asphalt and other low value of these products). Therefore, the light of crude oil is more popular, the international market prices are relatively high; and heavy crude oil is not so high popularity, the international market price is lower than the light crude oil.
