Embodiment Construction
[0136] The present invention will be further described below in conjunction with accompanying drawing.
[0137] In this example, the established PRSV-HV model is used to calculate the solubility of methane gas in water at 298.15K, 373.15K, 473.15K and 573.15K, 0.1-140MPa, and compared with the experimental data. For an overview of the calculation process, see figure 1 , using the step-by-step iteration method, the material balance is calculated first, and then the thermodynamic balance is calculated by combining the PRSV state equation and the HV mixing rule.
[0138] In this embodiment, what is calculated is the gas-liquid equilibrium isotherm of methane and water, that is, at a certain temperature, the relationship between the pressure and the solubility mole fraction of methane in the liquid phase is calculated. First, a set of temperature and pressure is given, and then the initial value of the equilibrium constant (K) is estimated, and the mole fraction (x, y) of the gas...
