Types and grades of oil.
Oil is currently the most important raw material for the production of energy, of course, as such an important raw material, it is naturally divided into various types, and no oil can be freely replaced or replaced by another oil.
Therefore, oil is an indispensable resource.
Petroleum is classified into different types according to its characteristics.
First of all, in terms of geographical location.
Geographically, oil can be divided into Far Eastern oil and Middle Eastern oil.
Far Eastern oil is mainly distributed in the mainland, Japan, India, Malaysia and other countries.
Middle Eastern oil is mainly distributed in Syria, the United Arab Emirates, Kuwait and other countries, and the two types of oil can be clearly distinguished.
The Far Eastern type of deep oil is darker in color and more viscous, and this oil tends to burn drier.
Middle Eastern types of oil are lighter in color, less viscous, and more flexible in their combustion.
The identification of petroleum is mainly based on the content of gases and other substances such as sulfur contained in this oil.
The different phases of these important substances will also affect the effectiveness of the use of these oils.
Depending on the type of oil, the price and use value of oil will also vary.
The scope of use of different oils is also different.
As an energy source with an extremely wide area of use, oil is naturally indispensable.
However, this oil is also gradually being depleted by people.
This has also led to a gradual increase in the price of oil and a more expensive use value.
Therefore, as an irreplaceable substance, the preservation of oil has become particularly important.
The preservation of this oil is also related to the quality of life of people in the future.
China's oil consumption.
The world's largest producer of energy resources is the name of the mainland.
At the same time, the continent is also among the best in the world in terms of oil consumption.
However, the oil produced by the mainland simply cannot meet such a huge consumption of the mainland, so the oil imported by the mainland from abroad is also quite an astonishing figure.
The amount of oil imported by the mainland every year far exceeds that of the United States.
At the same time, after importing so many oil resources, why does the mainland choose to export some of them?
What are the benefits of this?
How much of these oil resources are exported?
There are countless types of oil in the world, and at the same time, the amount of oil resources is unimaginable.
While we use oil, we should also use raw materials as sparingly as possible, so that people can use oil more sustainably.
Four major grades of oil
The grades of oil are mainly divided into four major grades, A, B, C and D.
Class A
Grade A oil belongs to an excellent oil, the aromatic content of this oil is larger, the viscosity is smaller, and the stability of viscosity is also better, there is a relatively low fluidity, reduction, metamorphism of a kind of oil, it also has a good anti-corrosion protection effect, so grade A oil is a very good oil.
Class B
B, C grade oil can be regarded as a kind of oil, B grade and C grade oil are relatively large, at the same time, the sulfur content of the two is also relatively high, the viscosity of the oil is also more.
In B, C grade oil, the fluidity is relatively poor, and the viscosity is larger, the viscosity is not good, and at the same time will cause certain damage to mechanical equipment, this oil is more commonly used to produce heat by combustion, in addition, B and C grade oil can also be filtered, and the decomposition process becomes A grade oil.
Class C
Grade C oil is similar to Grade B oil, with a higher concentration of oil and a higher sulfur content.
In fact, grade B oil and grade C oil have these characteristics compared to grade A oil, which are "flaws", but they can be used for tempering and refining, and turning them into grade A oil that burns heat and produces heat.
Grade D
Grade D oil is a very inferior oil, the concentration of oil is very deep, including a large number of mud, impurities, etc., this oil will produce a large amount of smoke and soot when burned, and will also cause serious pollution to the environment.
In addition, D-grade oil also contains a large number of toxins, has extremely dangerous combustion characteristics, is prone to explosion accidents, and is rich in paraffin, relatively dense, and has an extremely high freezing point, so it will crystallize at low temperatures, and the fluidity of the oil will become poor, so D-grade oil basically has no use value.
The world's four largest oil exporters.
There are also many countries in the world that are relatively rich in natural resources.
In these countries with abundant natural resources, there is also a very abundant need for these natural resources, and only when they themselves control these natural resources can they have a secure life.
The largest country in the world has the highest abundance of natural resources, including oil resources.
United States
The United States is the world's third largest oil producer, and at the same time, it is also the world's largest oil consumer.
The United States is arguably the only country in the world that exports less oil than it imports.
Russia
Russia is also a country with very rich oil resources in the world, the world's oil production, consumption and export volume is very amazing, and it is also one of the countries with the highest export of oil resources.
Saudi Arabia
Saudi Arabia is the world's largest oil exporter and one of the most oil-rich countries in the world.
Saudi Arabia's oil resources are very huge, and at the same time, the quality of this oil resources is also very good, which meets the needs of people in life, so Saudi Arabia exports almost all of its oil resources.
China
The mainland is the world's second-largest consumer of oil and the world's largest oil importer.
The mainland's oil resources are far from satisfying the mainland's needs, and the proportion of exported oil resources is also very small.
These exported oil resources are also usually imported through the continent itself.
The type of petroleum resources exported.
There are so many types of oil in the world that it is impossible to keep statistics on them.
When the mainland exports oil resources, it also chooses the right oil export according to foreign demand.
Commonly used evidence, natural gas, coal, iron ore, etc.
Petroleum resources are also divided into grade A and grade B according to their quality.
The oil resources exported are mainly some oil resources that cannot be used in the country, which are D-grade oil.
This kind of oil is not without use value on the mainland.
This kind of petroleum resources in the mainland, mainly used as lubricating oil, fuel oil, grease, etc. are very important aspects, used to polish metal, can also be used in chemical production, can also be used as a preservative.
However, in the mainland, the main use of D-grade oil is this, but the value of D-grade oil is not high, so the mainland will also choose to export this oil when exporting oil resources.
epilogue
The mainland is a country rich in natural resources and a major oil producer.
In the development of the mainland, the mainland's oil resources are also an indispensable part, but the mainland's oil resources are far from meeting the mainland's demand, so the mainland has to import oil from all over the world.
At the same time, the mainland will also select a part of its oil resources for export.
The mainland's oil resources are indeed very rich, but there are still many deficiencies in the protection of such oil resources.
