... of a modified Peng-Robinson EOS. Experimental observations identified a relationship between the third phase and the oil's pentane-insoluble fraction. The characterization uses a total of 16 components, with the heaviest two approximating the pentane-soluble and pentane-insoluble portions of the C 36+ fraction...
