Coking Drum Switch Handling:
Delayed coking unit, in a strict sense, is not a continuous process. Coke drums are operated in batches and downs stream fractionators and strippers are operated continuously. Each of the events during coking cycle , such as preheating, drum switch over , drum filling cause big disturbance to the downstream process.
Advance Process Control may not be applicable for this operation.
Can automating the SOP of Drum Switching improve the coking cycle?
