Reaction problems in delayed coking coke ovens
Thread Content
After the distillation column bottom oil is heated in the heater and then fed into the coke tower, how long does it take for this stream of oil to complete its reaction?
Is my question too strange? Waiting for a master to appear
The reaction has already begun inside the heating furnace; as long as the temperature reaches the required level for the reaction, it will start.
Controlling the flow rate inside the furnace tubes is crucial; steam injection is important and must be properly regulated to delay the regeneration of coke in the coke tower
The oil coming out of the fractionation tower is heated in a heating furnace, where it is required to stay for a short period of time inside the furnace tubes; thereafter it enters the coking tower, where it remains for a certain amount of time
It takes how long for that residue to reach the reaction temperature until coke and oil gases are produced!
This is closely related to the properties of the raw materials and the oil (carbon residue value), as well as the quality of coke required. You can calculate the reaction time by dividing the effective volume of the coke tower in your facility by the feed rate
It’s possible to roughly calculate the flow rate inside the furnace tube, but I’m not quite sure about the reaction time; I’ll study it further
By delay, it means preventing the raw materials from reacting in the furnace, and instead controlling the reaction to take place in the coke tower. Therefore, the linear speed is different, and efforts should be made to minimize the reactions inside the furnace tube.
What does delayed coking mean? ? ? ? ? The residence time is determined based on the process you have designed; it depends on factors such as the length of the furnace tubes and the amount of gas injected. Of course, a set value for the residence time is specified for each heating furnace, but this value still needs to be determined through practical experimentation during operation.
