Anonymous users2024-02-09Heavy oil, also known as fuel oil, is a dark black liquid, which is mainly blended with atmospheric oil, vacuum residue, cracking residue, cracked diesel and catalytic diesel in the processing process.
According to the classification method of international conventions, heavy oil is called sustainable oil, and as the name suggests, this oil is relatively viscous and difficult to volatile. So once it's on the shore, it's very difficult to remove. In addition, the impact of this oil on the marine environment is much more severe than that of non-persistent oils.
For example, after it enters the seawater, because it is relatively viscous, if the feathers of the seabird are stained with these oils, it will affect the seabird's inability to forage and fly, and at the same time, when the seabird combs its feathers, it will swallow this harmful oil into the stomach, causing the death of the seabird. There are also some fish species, especially juveniles and marine plankton, that are more affected by heavy oil. When you get to the beach, the oil sticks to the beach and is very difficult to clean.
Experts said that to deal with oil pollution, necessary oil spill emergency facilities such as oil booms, linoleum and carburetors can be used. Due to the strong adhesion of oil, farmers can use straw, hemp rope and other items to enclose oil and oil when oil pollution comes.

Anonymous users2024-02-07Different concepts, different difficulties in industrial production, and different uses.
1. The concept is different.
Heavy oil is a type of fuel oil, which is generally used in industrial boiler combustion, while light oil (naphtha) is a type of refined oil, which is generally used as a petrochemical raw material.
2. The difficulty of industrial production is different.
The production, transportation and refining of heavy oil is currently facing special challenges compared to light oil. In addition, heavy oil operating technology must be aware of the operating costs and long-term economics of heavy oil development. Heavy oil is an important energy resource, and heavy oil requires a very high level of industry and expertise.
3. Different uses.
Heavy oil is a relatively viscous lead substance, and light oil is not sticky. On **, light oil acts as a **softener, while heavy oil acts as a lubricating laxative.
What is Heavy Oil:
Heavy oil is highly viscous**, and it is called "heavy" because it has a higher density or specific gravity than light**. Heavy oil has been defined as any liquid oil with an API specific gravity of less than 20. Heavier** and lighter grades with different physical properties include higher viscosity and specific gravity, as well as heavier molecular composition.
What kind of oil is light oil:
Light oil refers to naphtha, which used to refer to the fraction with a boiling point higher than gasoline and lower than kerosene. However, if the boiling point is lower or higher than this, it is also often called naphtha. Light oil can be used as a petrochemical feedstock.
Light oil is obtained by ** distillation or petroleum secondary processing to produce the corresponding fraction. Its boiling point range depends on the need, usually a wide boiling range, such as 30-220. Light oil is an important raw material for the production of ethylene, propylene by tubular furnace cracking, and the preparation of benzene, toluene and xylene by catalytic reforming.

The specific gravity of heavy oil is generally in the calorific value of 10,000 11,000kcal kg. Its composition is mainly hydrocarbons, but also contains some sulfur and trace amounts of inorganic compounds.
Heavy oil is called a durable oil, and as the name suggests, this oil is relatively viscous and difficult to volatile. So once ashore, it's hard to remove. It is mainly made of atmospheric oil, vacuum residue, cracking residue, cracked diesel and catalytic diesel in the process of processing.
There is no precise definition of refined vegetable oil, and there is no corresponding industry standard. The so-called refined vegetable oil is a general term that refers to processed vegetable oil, refer to the wikiBrief refinement consists of one or more of the following processes: >>>More
Hydrocarbon oil is a kind of bioliquid new energy that can replace petrochemical diesel, and belongs to biomass renewable energy. It is a liquid fuel produced by lipid exchange reaction under the action of a catalyst with various lipid compounds (rapeseed oil, cottonseed oil and scraps of various vegetable oils) and methanol as raw materials, which is golden yellow. >>>More
Butter, also known as milk fat and butter oil, is a solid grease processed from milk, which is the product of filtering out part of the water from the thick object on the upper layer after stirring fresh milk. It is mainly used as a condiment, which is rich in nutrients and high in fat. Butter is made by separating the cream from the skim milk in milk, ripening the cream and stirring it. >>>More
The term "cell broadband" generally refers to fiber-to-the-cell, that is, LAN broadband. The whole community shares this optical fiber, and when there are not many people using it, the speed is very fast, and it feels like playing games and things. Theoretically, it can reach up to 100m at the fastest, but by the evening rush hour, the speed will be mediocre. >>>More
