C) What is the composition and flow rate of the hydrogen rich stream leaving the seperator? Report the composition in mol% and flow rate in kmol/h.

In addition to the product ammonia gas, industrial scale production of ammonia produces an output waste stream containing 60% hydrogen (H2),20% nitrogen (N2) and 20% other gases. With a focus on hydrogen fuel cells, you aim to recover hydrogen from this waste gas stream by separating it from nitrogen. To simplify the system, you can assume that "other gases" were removed already and you have a feed of 75% hydrogen and 25% nitrogen. This is fed into a separator. One stream coming out of the separator is rich in hydrogen, and this is your product stream. The other is 100% nitrogen and sent into the atmosphere. You feed 100kmol/h into the separator and 20kmol/h of pure nitrogen is fed into the purge unit A) (5 pts) Draw and label the process diagram for the process described above. Label all known and unknown quantities. You do not need to draw the products or exit streams for the purge unit, just end the diagram with the unit. B) (3 pts) Perform a degree of freedom analysis on the separator. As part of your analysis state the number of unknowns, number of equations and degree of freedom
