Dear all,

Feed incompatibility is normally a cause for fouling increase in the upper radiant section, due to asphaltene precipitation.
p-value is an analisys that is normally used to measure asphaltene precipitation tendency in other processes (like visbreaking, fueloil, etc).
Has anybody experience of the sucessful application of this analissy (or any other similar) to predict compatibility issues in Delayed coker feed? If so, what is the monimum p-value recommended?

Thanks for your help

Regards
