Phase Envelope Basics:
• Cricondenbar: Maximum P for two-phase
• Cricondentherm: Maximum T for two-phase
• Dew Point: First liquid forms from gas
• Bubble Point: First gas forms from liquid

Estimates phase envelope boundaries using Wilson K-value correlations with Stewart-Burkhardt-Voo (SBV) pseudo-critical mixing rules per Industry methodology.
Calculation Method:
K-values: Wilson correlation (1968)
Mixing: Kay's + SBV corrections
Properties: GPSA/GPA 2145 data
Key Applications:
Pipeline operating point verification
Separator inlet phase determination
Retrograde condensation assessment
Dense phase transport feasibility
Accuracy Note:
±5-10% for typical natural gas. Use process simulator (HYSYS, ProMax) with tuned EOS for detailed design.
