In the final stage of petroleum refining, petroleum coke was once regarded as "waste". Nowadays, the technology of replacing heavy oil with petroleum coke powder has become an important direction for the transformation of green industry. This technology not only realizes the efficient utilization of "waste resource utilization", practicing the circular economic development model, but also opens up a brand-new path for the application of new energy, precisely responding to the national green and low-carbon development policy, and providing high-quality solutions for cost reduction, efficiency improvement, energy conservation and emission reduction in various industrial fields.

I. Classification and Core Characteristics of Petroleum Coke

The performance of petroleum coke varies due to different production processes and raw materials. Different types of petroleum coke are suitable for different industrial scenarios. Among them, fine coke is the core raw material basis for achieving heavy oil substitution.

Needle coke: It features a clear needle-like structure and fibrous texture, and is mainly used in the manufacturing of high-power graphite electrodes in the steelmaking industry. It has strict requirements in terms of sulfur content, ash content, volatile matter and true density and other indicators. Our company's European version grinding mill, with the advantage of professional production technology, can precisely match the high-standard processing requirements of needle coke.

Sponge coke: With high chemical reactivity and low impurity content, it is an excellent raw material for the aluminum smelting industry and the carbon industry.

 Shot coke (spherical coke) : It is a regular spherical shape with a diameter ranging from 0.6 to 30mm. It is mostly produced from high-sulfur and high-asphaltene residual oil and is mainly used for fuel replenishment in industries such as power generation and cement.

 Powder coke: Produced through fluidized coking technology, it features uniform particle fineness (diameter 0.1-0.4mm), high volatile matter content and high thermal expansion coefficient. It cannot be directly used for electrode preparation and carbon production. However, after specialized processing, it is an ideal fuel raw material to replace heavy oil.

Ii. Petroleum Coke powder processing technology: Precise grinding to ensure efficient combustion

High-quality petroleum coke powder is the key to ensuring the effect of replacing heavy oil. Our company adopts standardized and intelligent processing procedures to ensure the stable quality of the finished product and meet the combustion requirements of various kilns.

Petroleum coke is first crushed by a crusher for the first stage, and then dried according to the moisture content requirements of the raw materials (the drying process can be omitted for some dried raw materials). Subsequently, it is vigorously ground through the core equipment, the European version grinding mill, and finally produced into petroleum coke powder that meets the personalized needs of customers. The finished products can be quantitatively, continuously, evenly and stably injected into the kiln for combustion through a professional conveying system, ensuring combustion efficiency and production stability.

After actual measurement, the combustion temperature of petroleum coke powder in a glass furnace can reach 1650-1730℃, which is fully equivalent to or close to the flame temperature of heavy oil combustion, and can precisely meet the strict temperature requirements of industrial production. Meanwhile, its ash content is comparable to that of heavy oil, and its sulfur content is lower than that of coal tar. The combustion process is more environmentally friendly and can effectively reduce pollutant emissions.

Iii. Core Equipment: European version trapezoidal grinding mill, empowering efficient grinding

The processing quality of petroleum coke powder cannot do without the technical support of core grinding equipment. Our company's European version grinding mill integrates multiple independent patented technologies, providing a strong guarantee for the petroleum coke powder grinding process. It has eight core advantages:

1. Green and environmentally friendly design: Low operating noise, strict control of dust pollution, and compliance with industrial environmental protection standards;

2. Grinding roller linkage pressurization: The technology is mature and stable, with higher grinding efficiency and ensuring stable output of finished products.

3. Arc-shaped air duct structure: Small air volume loss, good material fluidity, and improved overall efficiency of powder making;

4. Internal thin oil lubrication: The lubrication system is stable and reliable, extending the service life of the equipment and reducing maintenance costs.

5. Bevel gear integral transmission: Low energy loss, high transmission efficiency, further reducing production energy consumption;

6. Controllable finished product particle size: The fineness of the finished product can be precisely adjusted according to customer requirements, and the powder selection efficiency is high.

7. Resistance-free air intake volute: The small observation door design eliminates vortex interference, ensuring smooth air intake and enhancing grinding stability.

8. Curved surface replaceable blade scraper: The scraper is highly wear-resistant and easy to replace, reducing the difficulty of equipment operation and maintenance.

Iv. Technological Empowerment: Practicing Green Development and Jointly Creating Industrial Value

The technology of replacing heavy oil with petroleum coke powder is a vivid practice of the circular economy concept in the industrial field. It not only solves the problem of resource utilization of petroleum coke "waste", but also helps industrial enterprises reduce fuel costs and pollutant emissions, achieving a win-win situation of economic and environmental benefits.

Our company, relying on professional petroleum coke powder processing technology, core grinding equipment technology and a complete service system, provides overall solutions for petroleum coke powder to replace heavy oil in multiple industrial fields such as glass, cement and power generation. In the future, we will continue to focus on technological innovation, providing more high-quality products and services to help more enterprises achieve green transformation, jointly respond to the national dual-carbon strategy, and promote high-quality development of the industrial sector.
