Abstract Natural gas phase equilibrium diagram was drawn through analysis and simulated calculation of hydrocarbon dew point based on Peng-Robinson property equation. Compared to the saturated vapor pressure estimation suggested by GB/T 5274—2008, hydrocarbon dew point analysis of the phase could predict the liquefaction possibility accurately at certain pressure and temperature then to ensure the reliability of the standard gas mixture preparation values.
