Determine the percentage of liquid and vapor formed when a mixture containing the following mole fractions 0.1835 N2, 0.5506 H2, 0.2658 NH3 enters a flash separator at -25C and 20 bar. Data provided:

[1] N₂

[2] H₂

[3] NH₃

Components at the entrance:

Z₁ = 0.18

_Z2 = 0.54

Z₃ = 0.28

Input current:

F = 2439.8

L = 2439.8 - V

Distribution coefficients K:

K₁ = 1300

K₂ = 2400

P_3sat = 1.51779 bar

*For the calculation of the fugacity, ideality can be assumed because pure ammonia is obtained. An activity of 1 is assumed* 

The following equation can be used if necessary:

K3 = 7. P3sat 0.P P =4 7= 21F 2.F 22 23F 1 = L+(K1.V)) L +(K2V)) L +(K3.V))
