Abstract
Processes for rapidly and accurately predicting the fouling potential of a heavy petroleum fraction in a commercial refinery, informing the selection of one or more interventions to prevent or decrease the rate of said fouling. The process utilizes several specializedC Nuclear Magnetic Resonance procedures to more accurately quantify tertiary and quaternary bridgehead aromatic carbon in the heavy petroleum fraction This permits more accurate calculation of a Condensation Index for the heavy petroleum fraction to more accurately predict fouling potential of the fraction. When the condensation index is at or above a threshold value, the process implements one or more responses to improve operational efficiency of the commercial refinery.
