1. Limiting reactant, purge analysis: Consider the reaction for diatomic nitrogen combining with diatomic hydrogen to form ammonia (NH3). af Write out the balanced stoichiometric equation and determine which reactant is the limiting reactant, if the feed contains 40 moles/hr nitrogen and 100 moles/hr hydrogen. b. In a system with a purge, the amount of inert in the purge line needs to meet the amount of inert in the feed, in order for the system to operate properly and for no inert material to build up in the recycle lines. For the diagram given below, and an overall conversion of 90% for the limiting reactant, calculate the flows of nitrogen, hydrogen, ammonia and inert (in units of moles/hr) for the purge stream 4. At the condenser, all of the ammonia product goes to the "liquid product" stream, and none of the ammonia goes towards stream 3
