There are several reasons: poor backflow, hesitation to cool down too quickly, to avoid pressure buildup. Due to operational and process-related factors such as low steam injection pressure, low water supply volume, the properties of the oil, small cold coke channels, and so on – there are too many reasons. Your question is too general, making it difficult to provide a response
The cooling rate of coked coke is slow; how to solve this? First, may I ask what your coking cycle is? If the coking cycle is long, the cooling rate of the coke will be slower, but this isn’t the main reason. It could be that there isn’t enough time when using low or high steam supply; also, check to see if the downstream path is unobstructed.
That’s way too general; please provide some specific details
What is the temperature of the cold coke water? Is the volatile content high in petroleum coke?
Without an explanation of the phenomenon, it’s impossible to judge
We are part of the same unit; one of the reasons is poor backtracking, but that’s not the whole story； For cold coke, from the start of steam injection until all the water is removed and the tower is handed over, the process takes more than 10 hours when it comes to longer cases.
The speed of cold coking is primarily determined by the temperature of the coolant exiting the cooling tower at the top; lower temperatures result in slower cold coking. Other factors that influence this process include whether the flare system is functioning properly or if there is pressure buildup, the height of the coke pile, the quality of the coke, and the fact that pelletized coke cools more slowly.
Coking in the overhead oil and gas line? There are many factors such as raw material properties, coking cycle, and steam supply time
