Calculating flow rate of nitrogen

The feed of an ammonia synthesis reactor is 25% (lbmole) nitrogen with the balance hydrogen. The flow rate is 3000 kg/h at 65°C and 95 bar. Calculate the flow rate of nitrogen to the reactor in kg/hr.

So for 3000Kg/Hr feed we convert to lb mole feed rate=(3000/0.45359237)lb/hr =6613.868 lb/hr

So N2: H2 =1:3 in lbe mole in feed

1lbmole N2 =28 lb N2
1lbmole H2 =2.015 lb H2

So N2:H2 =3*2.016lb: 28Lb=6.048lb:28lb

So Each 34.048 lb feed has 28lb N2

So 1653.467lbmole/hr feed has =388.5026 lb of N2 = 388.5026lb*0.453.59237kg/lb =176.2218 Kg/Hr N2
