摘要:
A process for determining the incompatibility of crude mixtures (heavy, light) is based on the measurement of dynamic viscosity of crude mixtures using an electromagnetic viscometer having a mobile element (piston) move through the fluid to be measured at a constant force.

Density measurement of mixtures of heavy and light crudes using the vibrating tube densitometer technique determine incompatibility in the crudes mixture containing asphaltenes by determining the incipient point of asphaltenes incompatibility threshold in the mixtures of crudes.
摘要:
The present invention provides a new process of the transitiometric scanning technique to determine in an experimental way the minimum miscibility pressure of any sample of hydrocarbon at constant temperature (from the atmospheric temperature to 673 K) in the pressure interval of the atmospheric temperature to 400 MPa, including pressure at which the organic matter will precipitate due to the CO2 injection, based on a transitometric technique which has proved to be reliable, highly accurate and highly reproducible. The apparatus used is based on a highly accurate control of the pVT variables and the calorimetric determination of the present phase transitions during the injection process of gases into hydrocarbons. Accurate control of pVT variables enables the determination of the derivative thermodynamic variables useful to define the type of phase transition.
