The present invention includes a method for blending two or more petroleum feedstreams, petroleum process streams, or combination thereof, at least one of which includes the solute asphaltenes so that the asphaltenes remains a solute. The blending method includes the steps of determining the insolubility number, I.sub.N, for each feedstream, determining the solubility blending number, S.sub.BN, for each feedstream, and combining the feedstreams in order of decreasing S.sub.BN number of each feedstream such that the solubility blending number of the mixture is greater than the insolubility number of any component of the mix, when the solubility blending number of any of the feedstreams or streams is equal or less than the insolubility number of any of the streams.
A method for blending two or more petroleum feedstreams, petroleum process streams, or combinations thereof, at least one of which includes solute asphaltenes so that said asphaltenes remain a solute and thus minimize fouling or coking of process equipment at or downstream of the blending comprising:
A method of selecting compatible petroleum feedstreams, petroleum process streams, or combinations thereof, for blending comprising:
