QUESTION 4 (PO2, CO3, C3,C5) In a classical industrial synthesis, ammonia and carbon dioxide are compressed at certain temperature and pressure and formed ammonium carbamate, NH,COONH. Dehydration of ammonium carbamate to produce urea, CO(NH)2 and water are as below: NH, * CO, NH,COONH, NH,COONH, CO(NH2) + HO The feed to reactor contain ammonia, carbon dioxide and inert gas. A sample of reactor effluent is then analyzed and found to contain 31.2 mol % ammonia, 6.8 mol % ammonium carbamate, 25.65 mol % urea, 1.6 mol % CO, 9.1 mol % inert gas and the balance is water. Basis of this process is 100 mol/h of effluent stream. With the aid of a balance stoichiometry equation and a complete flow chart for the process, determine the molar composition at the feed of reactor and the percentage conversion of ammonium carbamate.

In a classical industrial synthesis, ammonia and carbon dioxide are compressed at certain temperature and pressure and formed ammonium carbamate, NH4COONHCO2. Dehydration of ammonium carbamate to produce urea, CO(NH2)2 and water are as below: NH2+CO2NH4COONH2NH4COONH2CO(NH2)2+H2O The feed to reactor contain ammonia, carbon dioxide and inert gas.
