Ask a little about coal coking , what is coal coking

Where is dude? I'm from Jining, and the coal here is also very developed. I work for a large coal chemical company.

Taking our coking plant as an example, there are mainly coal preparation, machine coke, chemical production, methanol, power, electrical instrument and other branches, among which coal preparation and machine coke positions are relatively poor because they have to deal with coal and coke, while power and electrical instruments require boilers, electrical and other related majors, which are more suitable for chemical production according to your situation.

Our company's chemical production plant is mainly used to purify gas, produce tar, crude benzene, ammonium sulfate, sulfur and other products, which are not considered coal chemical majors, such as chemical technology and engineering majors.

Positions, mainly drum cooling, desulfurization, ammonium sulfate, crude benzene and central control room, etc., generally graduated from school to learn chemical companies plan to train well, will let you go to the chemical industry to learn all positions, and so on the process and equipment have mastered the position of chemical technician, equipment and other positions.

There's a lot more to say, and if there's anything else you want to ask, you can ask again.

Hehe, the brother upstairs said well, but the environment of the coking plant is really not flattering, so if you go, you should think about it.

Now in the centralized control of coking CDQ, the environment is slightly better, but the best thing is to mix a technician, and the road will slowly get better.

Hello, the coal index for coal and coke is clean coal. The coking plant uses refined coal, and there are several kinds of refined coal, one-third of which is coking coal, main coking coal, high sulfur fertilizer coal, No. 2 lean coal, and gas coal. The indicators of the main coking coal are:

Ash ; combustible base volatile content 18 24%; Sulfur ; g75；y16mm。Main coking coal: ash content, sulfur content, volatile content, g value, y value coking coal:

75>18。The main coking coal is mainly used for the treatment of iron and steel. Main coking coal refers to the national coal classification standard, the term for bituminous coal with medium coal metamorphism and strong cohesiveness, a kind of coking coal, an important part of coking coal blending, the strongest coking, good meltability, large coking expansion, wear resistance, and refined coal refers to the general term of washed coal products that have been washed and processed for coking or other purposes.

The types of coal that can be used for coking coal or coking coal blending include gas coal, gas fertilizer coal, 1 3 coking coal, fertile coal, coking coal, lean coal, and lean coal.

Coking coal coking and cohesiveness are the most important indicators. In general, there are very few coal grades that meet these two conditions and other indicators (such as ash, sulfur, volatile, moisture, etc.) at the same time. Therefore, it is generally coal blending, and several kinds of coal are proportioned according to a certain proportion to meet the requirements of coking coal.

If you want to say that the amount is large, it must be more coking coal and lean coal.

The form of coal is relatively not very good now, and coking coal is generally 1000-1200 yuan tons. It depends on factors such as the quality of your coal.

Coal coking, also known as coal high-temperature dry distillation, is a coal conversion process that uses coal as raw material, heats to about 950 under the condition of isolated air, produces coke through high-temperature dry distillation, and obtains coal gas, coal tar and other chemical products at the same time. In order to ensure the quality of coke, the most basic requirements for selecting coking coal are volatile, cohesive and coking; The vast majority of coking coal must be washed to ensure the lowest possible ash, sulphur and phosphorus content.

When choosing coking coal, it is also necessary to pay attention to the expansion pressure of the coal during the coking process. Coking with low volatile coal, due to its high colloidal viscosity, is prone to high expansion pressure, which will cause damage to the coke oven masonry, and needs to be solved by coal blending and coking. Products & Uses:

There are three types of coking products: coke, coal tar, gas and chemical products.

Coke. More than 90% of the most important products of coking are used in blast furnace ironmaking, followed by foundry and non-ferrous metal smelting industries, and a small amount is used to produce calcium carbide, carbon disulfide, elemental phosphorus, etc. Coal tar.

The important product of the coking industry, its output accounts for about 3% and 4% of the furnace coal, and its composition is extremely complex, and in most cases it is specially separated and purified by the coal tar industry and utilized.

Gas and chemical products. The ** rate of ammonia accounts for about the coal in the furnace, and it is often used as the final product in the form of ammonium sulfate, ammonium phosphate or concentrated ammonia. The crude benzene ** rate accounts for about 1% of coal.

Among them, benzene, toluene, and xylene are all raw materials for the organic synthesis industry. The first grade of sulfur and thiocyanide compounds is not only for economic benefits, but also for the needs of environmental protection.

<> upgrading coal is coking, which is in the semi-coke. As a raw material for coal-fired power generation, coal-to-natural gas, coal-to-methanol and further deep processing, high-quality coal can realize the separation and reasonable combination of coal components under the premise of clean and environmental protection, improve the carbon and heat conversion rate of coal resources, enhance the self-sufficiency of China's oil and natural gas, and ensure the security of the national energy strategy. Coal upgrading, also known as co-carbonization, is a process of coking with different additives mixed with coal for the main purpose of improving the quality of coke.

In petroleum processing, coking is the abbreviation of residue coke, which refers to the process of deep cracking and condensation reaction of heavy oil under high temperature conditions of about 500 degrees Celsius to produce gas, gasoline, diesel, wax oil and petroleum coke.

Summary. Coal coking is also known as coal high-temperature dry distillation. Coal is used as raw material, heated to about 950 degrees Celsius under the condition of isolated air, and coke is produced by high-temperature dry distillation, and coal gas, coal tar and other chemical products are obtained at the same time.

The coke produced by it can be used for ironmaking, and a small amount is used as a chemical raw material to make calcium carbide, electrodes, etc. In short, coal is coking so that all components can be used efficiently, and using gas as fuel is much cleaner than burning coal directly.

Coal coking, also known as coal quiet and bright charcoal high-temperature dry distillation. Coal is used as raw material, heated to about 950 degrees Celsius under the condition of isolated air, and coke is produced by high-temperature dry distillation, and coal gas, coal tar and other chemical products are obtained at the same time. The coke produced by it can be used for ironmaking, and a small amount is used as raw materials for the manufacture of calcium carbide and electrodes.

In short, coal is coking, so that all components can be molded and effectively used, and using coal gas as fuel is much cleaner than burning coal directly.

That's not the right question for me.

That's what I asked. What is the significance of coking of coal in coal chemical industry.

That's right, the main significance of the development of the coal coking industry is to produce high value-added chemical products. I just concretized it.

What is this meaning, you are not good at all, meaning is beneficial to something.

Isn't it advantageous to produce high value-added chemical products and make effective use of each of them?

The main products of coal coking include coke, coal gas, coal tar, etc. These products have a wide range of application value.

Coke is an important raw material for metallurgy, chemical and other industries, which can be used to manufacture steel and carbon materials with equal wide bonds;

Coal gas is an important energy source, which can be used for city gas, chemical raw materials, etc.;

Coal and land tar can extract many useful chemical products, such as benzene, phenol, solvent oil, etc.

At the same time, coal coking can also use industrial waste heat to improve energy efficiency.
