Phase identification diagrams. (a) Ternary fluid component discrimination diagram, using C1 + N2, C2–C6 + CO2, and C7+. (b) C5+ versus C1/C5+ discrimination diagram. (c) Block discrimination diagram, and (d) Z value discrimination and Z1-Z2 factor discrimination. Z = \(\:\left({C}_{1}+{C}_{2}+{C}_{3}\right)/{C}_{5+}+{C}_{2}/{C}_{3}\); Z1 = \(\:\left(0.88\times\:{C}_{5+}+0.99\times\:{C}_{1}/{C}_{5+}+0.97\times\:{C}_{2}/{C}_{3}+0.99\times\:F\right)/{C}_{5+}\), Z2 = \(\:\left(0.88\times\:{C}_{5+}+0.99\times\:{C}_{1}/{C}_{5+}+0.97\times\:{C}_{2}/{C}_{3}+0.99\times\:F\right)/{C}_{5+}\), where F = \(\:\left({C}_{2}+{C}_{3}+{C}_{4}\right)/{C}_{5+}\).
