It is desired to make a preliminary estimate for a plant separating 10 mol s-1 of pure Carbon Dioxide and 100 mol s-1 of pure Nitrogen, each at 200 kPa (ambient pressure) and 30C, from a Nitrogen/Carbon Dioxide binary mixture at the same temperature and pressure. Calculate the minimum amount of energy required to operate the process.

a) -90.08 kJ

b) 1.05 kJ

c) -85.76 kJ

d) 84.42 kJ
