METHOD FOR ESTIMATING SEDIMENT CONTENT OF A HYDROPROCESSED HYDROCARBON-CONTAINING FEEDSTOCK |
摘要 |
Disclosed herein is a method of estimating sediment content of a hydroprocessed hydrocarbon-containing feedstock. The method involves the steps of: (a) precipitating an amount of asphaltenes from a liquid sample of a first hydroprocessed hydrocarbon-containing feedstock having solvated asphaltenes therein with one or more first solvents in a column; (b) determining one or more solubility characteristics of the precipitated asphaltenes; (c) analyzing the one or more solubility characteristics of the precipitated asphaltenes; (d) determining asphaltene content of the liquid sample from the results of analyzing the one or more solubility characteristics of the precipitated asphaltenes; (e) determining one or more asphaltene stability parameters of the liquid sample from the results of analyzing the one or more solubility characteristics of the precipitated asphaltenes; and (f) correlating the asphaltene content and one of the asphaltene stability parameters of the liquid sample to estimate sediment content of the liquid sample. |
