f) The gas product stream from the reactor which consists of ammonia and un-reacted reactant is fed to a liquid-gas separator. Objective of the separator is to condense the ammonia and recycle the unreacted reactant. In the separator, the gas mixture is in equilibrium with its liquid. The liquid phase consists only of ammonia leaving the separator as a liquid outlet stream. On the other hand, the gas phase consists of non-condensable raw materials N₂ and H₂ leaves the separator as a recycle stream. Composition of the outlet gas and liquid streams from the separator are as in part c). Use the process condition and Raoult's law, determine suitable temperature (T) of the separator when system pressure (P) is set within the range of 8-10 atm. To determine the T, please state which condition should be considered between bubble point temperature and dew point temperature; and justify the choice. You may use goal seek in excel in solving the problem. Some errors are detected during the process and suddenly the temperature of the separator increases to double the T value. Comment on how the temperature affects the efficiency of the separator when pressure is set to constant.
