Abstract:
A method for coke removal in delayed coker drums is provided. The method comprises the steps of draining from the drum of substantially free-flowing coke, performing a vibration signature analysis on the drum to identify whether and where any coke remains attached to the interior wall of the drum after the draining step, and cutting the coke from the areas identified by the signature analysis step.
