In the production of ammonia, the amount of nitrogen fed is 50 mol hr-1 set by the stoichiometric ratio of hydrogen to nitrogen for the feed stream (1). In addition, the fed nitrogen contains 0.2 mol hr-1 of inert gases (argon), which gradually build up in the recycle stream until the process is affected adversely. The single pass conversion is 20%. If all NH3 is removed in a separation step, and a purge stream (6) of 2 mol hr-1 is used to maintain the Ar mol percentage in the recycle stream at 10%. a. Calculate the composition of the purge stream. b. What is the mass% of the feed? (MW N: 14gmol-1 H: 1gmol-1Ar: 40gmol-1) c. Determine the production rate of ammonia in mol hr-1 d. Calculate the flowrate of N2 (entering the reactor). PLEASE EXPLAIN IN GREAT DETAIL

Solutions

Expert Solution

The process diagram of the process and the required material balances are applied on the system as shown below. It is important to note that in question, as N2 and H2 are fed in stoichiometric proportion in feed, so through out the process, they will be present in stoichiometric proportions.
