The volatile content of petroleum coke indicates the coking temperature
The volatile content of petroleum coke indicates its coking temperature. The coking temperature of kettle coke is high, up to about 700 ℃, so the volatile content of kettle coke is low (3% ~ 7%), while the coking temperature of delayed coking petroleum coke is only about 500 ℃, so the volatile content is up to 8% ~ 15%. The volatile content of delayed coking petroleum coke depends not only on the coking temperature, It is also related to the loading time of residual oil into the coking tower and the conditions of blowing steam into the coke layer. The volatile content of coke discharged from the same tower is also very different. For example, the coke at the bottom of the tower has dense structure, large bulk density and low volatile content, while the coke at the top of the tower has loose structure and much higher volatile content. The volatile content of petroleum coke has little impact on the quality of carbon products, but it has an impact on the calcination operation. It is difficult to calcine petroleum coke with high volatile content in rotary kiln or tank furnace with general structure. The calcination equipment needs to be modified to meet the needs of calcining high volatile petroleum coke.
Caustic Soda Transportation
Caustic soda transportation is dangerous goods transportation, because caustic soda is strongly irritating and corrosive. Once the skin accidentally touches caustic soda, it will cause burns immediately; if swallowed, it will cause burns of the digestive tract, mucous membrane erosion, bleeding and even shock. Moreover, caustic soda can also produce harmful toxic fumes, which will cause great harm if it is not properly prepared and inhaled into the body. Therefore, in the process of transporting caustic soda, it is necessary to prepare in advance and pay attention to details.
1. The requirements for the driver are quite high, and special training is required to fully understand the performance of caustic soda and emergency measures in case of accidents, and understand the transportation rules of caustic soda, and strictly follow the regulations.
2. To ensure the safety of the transportation vehicles, before transporting caustic soda, a comprehensive inspection of the transportation vehicles is required to see whether the vehicles are in good condition and whether there are hidden safety hazards. Detailed inspections ensure the safety of the transportation vehicles.
3. Handling staff should take protective measures. When handling, employees need to take precautions, wear caustic soda protective clothing and protective gloves, and in the process of handling, need to lightly load and unload to prevent damage to caustic soda packaging, resulting accident.
4. The vehicle is sealed. After the loading is completed, the transportation vehicle needs to be sealed to avoid moisture during the transportation of caustic soda, especially during rainy or cloudy days.
