ABSTRACT:
The present invention includes a process for blending two or more petroleum oils, any component of which may be an unprocessed crude oil or a processed oil derived from petroleum, in a manner to minimize fouling and coking of refinery process equipment. The blending method includes the steps of determining the insolubility number, I, for each oil, determining the solubility blending number, S, for each oil, and combining the petroleum oils in the proportions in order to keep the solubility blending number of the mixture higher than 1.4 times the insolubility number of any oil in the mixture. The present invention also includes selecting petroleum oils to minimize fouling.
