As we know some refinery charge their DCU with VR cut point of 560C or even higher. Could we relate our coke fine with the low VR cut point?

To mitigate coke fine problem you can also check on your Heater outlet temperature and Crude/VR composition. Author Posts You must be logged in to reply to this topic.
