Phase Envelope
Important Terms Critical point: The critical point for a multicomponent mixture is referred to as the state of pressure and temperature at which all intensive properties of the gas and liquid phases are equal. At the critical point, the corresponding pressure and temperature are called the critical pressure Pc and critical temperature Tc of the mixture.
Bubble-point curve: The bubble-point curve is defined as the line separating the liquid-phase region from the two-phase region.
Dew-point curve: The dew-point curve is defined as the line separating the vapor-phase region from the two-phase region.
Important Terms Cricondenbar
is
the
maximum
pressure above which no gas can be formed regardless of the temperature. The
corresponding
temperature
is
called cricondenbar temperature.
Cricondentherm
is
the
maximum
temperature above which liquid can not be formed regardless of the pressure. The corresponding pressure is called cricondentherm pressure.
Reservoir Classification Oil reservoirs: If the reservoir temperature T is less than the critical temperature Tc of the reservoir fluid, the reservoir is classified as an oil reservoir. Gas reservoirs: If the reservoir temperature is greater than the critical temperature of the hydrocarbon fluid, the reservoir is considered a gas reservoir. Retrograde Condensation Region: Lowering the pressure isothermally leads to the formation of liquid phase.
