Summary

  1. 1.

    Data on the densities of narrow fractions obtained in the distillation of crude oils can be used to evaluate the chemical nature of these fractions and to calculate constants characterizing the fractions, such as the critical constants, molecular weight, enthalpy of liquid and vapor, etc.

     
  2. 2.

    Empirical formulas have been found for determining the densities of 10–50°C fractions on the basis of the known density of the crude, and also on the basis of the normal average boiling point of the fraction from the initial boiling point (with an accuracy within 0.0030–0.0100).

     
  3. 3.

    Complete agreement has been noted in the relationships in distribution of components by density in sour crudes produced in various districts and from different horizons in a vast region from the Volga to the Lena; such agreement can be explained by identity of the starting materials and conditions of oil genesis. The position of the fraction relative to the 50% point on the TBP curve has great importance in characterizing the fraction.
