The fresh feed to an ammonia production process contains 24.5 mole % nitrogen, 73.5 mole% hydrogen, and the balance inert (I). The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor in which a 25% single-pass conversion of nitrogen is achieved. The products pass through a condenser in which essentially all of the ammonia is removed, and the remaining gases are recycled. However, to prevent buildup of the inert in the system, a purge stream must be taken off. The recycle stream contains 8 mole% inert. Using a basis of 1000 kmol/h fresh feed, draw a labeled flowchart of the process and calculate ALL unknown flow rates and compositions (use 3 digits after decimal point) in the flowchart. and calculate the overall conversion of nitrogen. [Hint: use component flow rates for the streams going in/out of the reactor and separator]
