ABSTRACT:
A method for easily and quickly determining the tendency of a petroleum fraction (oil or resid) to foul in refinery equipment comprises determining the ratio of the saturates or aromatics (polar, neutral or total): asphaltenes for the petroleum in question and comparing this ratio with a plot of ratios and fouling tendencies for a set of prior oils or resids. It has been found that the ratio and the relationship to fouling are completely consistent and reproducible phenomenon which thereby provide a rapid means for a substantially quantitative measure of fouling tendency.
