considering unbalanced reaction N2 + H2 NH3, which reaches thermodynamic equilibrium in the reactor. The feed to the reactor (not the fresh feed to the process) enters at 200 mol/hr and contains mole fractions of 0.2 N2, 0.6 H2 and the balance inerts (I). The mole fraction of hydrogen in the reactor effluent is 0.2. The reactor effluent is sent to a distillation column where all of the ammonia exits as a pure NH3 stream from the bottom of the column and the remaining components leave the top of the column. 6.5% of the stream leaving the top of the distillation column is purged and the rest is recycled. The recycle stream is mixed with the fresh feed before entering the reactor.

A. Draw the process flow diagram. Number the streams. Label the components (nitrogen = N, hydrogen = H, ammonia = A, inerts = I) present in each stream.

B. Calculate the component molar flow rates (mol/hr) for the streams exiting the first distillation column.

C. Find the component molar flow rates (mol/h) of the fresh feed.

D. If the mole fraction of hydrogen in the reactor effluent increases by 10%, the equilibrium constant for the reactor will: INCREASE, DECREASEor STAY THE SAME
