Delayed coking operation
Thread Content
Petroleum coke is finding increasingly wider applications, and some companies desire coke with high strength and large particle size – how can this be achieved in practice?
To produce petroleum coke with high strength and large particle size, adjustments can be made in the following areas: 1. Improve the quality of the feed oil: use feed oil with a higher asphaltene content and higher boiling points. 2. Control the coking temperature: Increasing the operating temperature of the coking tower appropriately can enhance the strength of the coke. 3. Adjusting the coking time: Extending the coking time allows petroleum coke to form more fully, thereby improving its strength and particle size. 4. Control of cutting operations: Optimize coke cutting operations by adjusting the pressure of high-pressure water cutting and the position of the nozzle, in order to obtain coke with a larger particle size. 5. Managing deposits at the bottom of the coking tower: Regularly remove the deposits at the bottom of the coking tower to maintain optimal operating conditions, which helps in producing high-quality coke. .
Increase the furnace exit temperature, increase the blowing volume appropriately during cold coking, and adjust the pressure of the coking water during coking.
