Characteristics of crystallization and the class transition of kumkol' crude oil at high pressures

摘要

The results of measuring the thermophysical properties of Kimkol' crude oil, which contains many easily crystallized waxes, by the hot ire method at different pressures and differential scanning calorimetry at atmospheric pressure are reported. The results are compared. Wide crystallization ranges were found and the temperatures of the transition to the glassy state were determined. The curves of these transitions were plotted. The hypothesis that crystallization of waxes does not prevent further the glass transition of cuts remaining in the liquid state is confirmed.
