Drain water after the cold coking in the delayed coking unit is completed
Thread Content
What are the potential dangers of forgetting to open the breathing valve when releasing water?
Don’t worry; the water cannot be completely drained without opening the breather valve. The operator inside will check the level gauge of the coke tower and alert the operator outside to check the process
Besides not being able to release all the water, could the tower collapse?
Failing to operate the breather valve will not cause the tower to collapse. I’ve seen cases where, at startup, steam was used to expel air and then cold diesel was introduced directly, which caused the tower to collapse.
I know there’s a refinery where, when releasing water, the breathing valve wasn’t turned on, which caused the coke tower to collapse
Wouldn’t that make one a laughingstock in the industry?
Sometimes very simple mistakes can lead to significant losses
Sometimes, even seemingly simple steps can give rise to serious problems. Therefore, in industries such as oil refining and chemical manufacturing, no step should have any issues
