Abstract
Disclosed herein is a method of predicting sediment content of a hydroprocessed hydrocarbon product. The method involves: (a) precipitating an amount of asphaltenes from a liquid sample of a first hydrocarbon-containing feedstock having solvated asphaltenes therein with one or more first solvents; (b) determining one or more solubility characteristics of the precipitated asphaltenes; (c) analyzing the one or more solubility characteristics; (d) determining asphaltene content of the liquid sample from the results of analyzing the one or more solubility characteristics; (e) determining one or more asphaltene stability parameters of the liquid sample from the results of analyzing the one or more solubility characteristics; and (f) correlating the asphaltene content and one of the asphaltene stability parameters of the liquid sample with at least two operation conditions associated with a refinery to predict sediment content.
