PROCESS FOR PREPARING BLENDS OF BITUMEN HAVING KNOWN STABILITY PROPERTIES

摘要

Bitumen may be prepared by obtaining an inflection point value for a mixed bitumen product stream sample, and modifying the mixed bitumen product stream when the inflection point value occurs at a ratio of less than about 2 mL of added non-solvent per 1 gram of the mixed bitumen product stream sample. The inflection point value may correlate to the stability of the mixed bitumen product stream based on the amount of added non-solvent. The mixed bitumen product stream may have or include at least two bitumen feed streams.
