Phase and glass transitions in crude oils and their fractions at high pressure

• Phase and glass transitions in crude oils and their fractions were detected at high pressures (up to 2 GPa) and different temperatures, both in isobaric and isothermal measurements, using transient hot-wire method and DSC. Glass transition point is found to be independent on wax, asphaltene and pitches content. Its position changes on boiling out different components of light fraction, showing strong dependence on boiling temperature.
