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.
Claims11
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 comprising:
- (a) determining the insolubility number, I, for each oil.
- (b) determining the solubility blending number, S, for each oil;
- and
- (c) combining said petroleum oils such that the solubility blending number of the mixture is always higher than 1.4 times the insolubility number of any oil in the mixture.
A method for selecting a petroleum oil for blending with an oil or a mixture of oils that would otherwise be nearly incompatible to minimize fouling and coking in subsequent processing comprising selecting said oil for blending such that it has a solubility blending number higher than 1.4 times the insolubility number of any oil in the mixture and an insolubility number lower than at least one other oil in the mixture.
