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

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.

Suppose the feed to a continuous reactor for ammonia synthesis consists of 100 mol/s of nitrogen, 300 mol.s-1 of hydrogen, and 1 mol/s of argon. For a fractional hydrogen conversion of 0.6, calculate the outlet flow rate of hydrogen, the extent of reaction, and the outlet flow rates of nitrogen and ammonia. N2+3H2=2NH3

26 mol/hr of stream 1 (gas, at 1.1 atm and 0°C) containing 30% (mol basis) propane and rest butane is mixed with a second stream (gas, at 1.1 atm and 45°C) containing 60% (mol basis) propane and rest butane. The output stream is 70 mol/hr (gas, at 1.1 atm). The relative enthalpies as a function of temperature (T is in °C) are given as: H (J/mol) for propane = 91*T and H (J/mol) for butane= 121*T a) What is the...

1. Wet air containing 60.4 mol% of pure water at 82.5˚C is fed to a dehumidifier at a rate of 185 mol/hr. Outlet of the dehumidifier consists of 2 streams – one stream of drier air and the other stream is pure liquid water. The outlet streams are in vapor-liquid equilibrium at 812 mmHg and 31.7oC. a) Draw the process flow diagram, number the streams, and label the components in each stream. b) Find the component mole flow rates (mol/hr)...
