Figure 7From: Natural gas at thermodynamic equilibrium Implications for the origin of natural gasThermodynamic equilibrium and gas dryness. Q = (C1)*(C3)/(C2)2. The data is taken from Fig. 6. The black line passing through the data is the equilibrium curve, where Q approaches the equilibrium constant K (10.4) with gas dryness: Q = 10.4(1-e-α(C1/C2+C3))), α was set to 0.1 to fit the data.Back to article page
