What Precautions Should Be Taken While Handling Graphite Petroleum Coke?
When handling graphite petroleum coke, you need to pay attention to the following matters:
Safety:Graphite petroleum coke is a carbonaceous material, so fire and explosion protection need to be paid attention to during handling. Avoid contact with fire sources, static sparks and other fire sources, ensure that the working environment is well ventilated, and prevent dust accumulation from causing explosions.
Dust protection:Graphite petroleum coke may produce dust during processing, and long-term inhalation may have an impact on health. Operators should wear appropriate dust masks and protective glasses to ensure that personal protection measures are in place.
Storage and transportation:Graphite petroleum coke should be stored in a dry, ventilated, and cool place, away from direct sunlight and high temperatures. During transportation, ensure that the packaging is complete to avoid damage and leakage.
Handling and processing:When handling and processing graphite petroleum coke, appropriate measures should be taken based on its physical and chemical properties. Avoid using too much force or high speed to avoid creating excessive dust or causing sparks.
Environmental protection:When handling graphite petroleum coke, you need to pay attention to environmental protection to avoid pollution to the surrounding environment and ecology. Pollutants such as waste water and exhaust gas should be properly treated and comply with environmental protection requirements.
Personal protection:Operators should wear protective clothing, gloves, shoes, etc. that meet the requirements to avoid contact with graphite petroleum coke, which may cause irritation to the skin and eyes. At the same time, regular health check-ups should be carried out to ensure good health.
Production Process of Graphite Petroleum Coke
The production process of graphite petroleum coke mainly includes the following steps:
Choose high-quality petroleum coke as raw material. Petroleum coke is a petroleum product obtained after crude oil is distilled to separate light and heavy oil, and then the heavy oil is thermally cracked. It is black and porous, with a carbon content of more than 80% and an ash content of generally less than 0.5%.
Petroleum coke is screened, crushed and pulverized to break it into appropriate particle sizes.
Put the crushed petroleum coke into a high-temperature furnace for roasting. This step helps purify and upgrade the petroleum coke, giving it a higher calorific value and better physical properties.
The roasted petroleum coke is cooled to lower its temperature. Then, defective products are removed through mechanical sorting to ensure product quality.
Graphitize the cooled petroleum coke. High-temperature graphitization treatment is usually used, that is, petroleum coke is put into a graphitization furnace and graphitized at high temperature (such as 2800°C-3000°C). During this process, the remaining impurities in the petroleum coke will gradually evaporate, and the carbon elements will rearrange to form a tighter graphite structure, ultimately forming high-purity graphitized petroleum coke.
After graphitization, the petroleum coke is finely processed and packaged, and then can be sold out of the factory and used to make electrodes, cathodes, boiler fuel and other industrial products.
How to Store Graphite Petroleum Coke?
Moisture-proof
Graphite petroleum coke should be stored in a dry, ventilated place to avoid moisture. Moisture can cause hygroscopicity and spontaneous combustion of graphite petroleum coke, so the relative humidity of the storage environment needs to be kept low.
Prevent spontaneous combustion
Graphite petroleum coke may spontaneously ignite during storage, so it needs to be turned and inspected regularly to ensure good heat dissipation of graphite petroleum coke. If the local temperature is found to be too high or there are signs of spontaneous combustion, immediate measures should be taken to deal with it.
Classified storage
Different brands of graphite petroleum coke should be stored separately to avoid confusion. At the same time, it should be ensured that the storage area is clearly marked and numbered to facilitate management and search.
Fire safety
Graphite petroleum coke is a flammable substance, so fire prevention facilities such as fire extinguishers, fire hydrants, etc. should be installed in the storage area. At the same time, smoking, using open flames and other behaviors that may cause fire are prohibited in the storage area.
Regular inspection
Regularly inspect the stored graphite petroleum coke to ensure that its quality and quantity have not changed. If any abnormality is discovered, it should be handled and reported promptly.
