The fresh feed to an ammonia process contains 24.75% mole Nitrogen, 74.35% mole Hydrogen, and the balance inerts. The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor in which 0.25% single-pass conversion of nitrogen is achieved. The product pass through a condenser in which essentially all of the ammonia is removed and the remaining gases are recycled. However, to prevent build up of the inerts in the system, a purge stream must be taken off. The recycle stream contains 12.5% mole inerts. Calculate the overall conversion of Nitrogen, the ration n (moles purge gas/ mole of as leaving the condenser), and the ratio (moles fresh feed/ mole fed to the reactor)

2. 100 mol/h of gaseous ethane is burned with excess air. The fuel is mixed with air before entering the furnace; fuel-air mixture is fed to the furnace at 25oC and 1 atm. All the ethane is consumed in the combustion reaction that occurs in the furnace. A cooling water jacket surrounding the furnace removes all of the heat generated by the combustion reaction. The stack gas leaves the furnace at 25oC and 1 atm and contains 5.32 mole% CO2, 1.60% CO, 7.32% O2 and the balance H2O and N2.a. Use Hess’s Law and the Heat of Combustion to calculate ∆??o (kJ/mol) for complete and incomplete combustion of ethane. b. Calculate the molar percentage of ethane in the fuel gas and the percentage excess air fed to the reactor.c. Calculate rate of heat transferred to the cooling water jacket in kW.

One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene. C,H,CH; + H, C,H, + CH4 A stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen. The reaction products at 550 °C enter a condenser, where they are cooled to 41.0 °C. A vapor stream containing Y5CH, = 0.600 mol CH,/mol leaves the process, and a liquid stream containing x66 = 0.810 mol benzene/mol and x6 = 0.190 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at n7 = 668.0 mol/h and contains y7h = 0.9000 mol benzene/mol and y7 = 0.1000 mol toluene/mol. The bottoms of the column contains X8b = 0.250 mol benzene/mol and xgt = 0.750 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at ni = 1183 mol H,/h. This process is carried out at 760 mmHg. A n, mol/h mol H/mol YSH2 YSCH, mol CH_/mol Ysh mol b/mol Ys mol t/mol n̟ mol/h n, mol/h Condenser Улн, тol H/mol Усн,…

11.7 mole dichloromethane (CH2Cl2) enter a reactor with 21.6 mole hydrogen (H2) and 37.5 mole oxygen (O2).  The following reaction takes place: CH2Cl2 + H2 + 3/2 O2 → COCl2 + 2 H2O 6.4 mole of H2O are produced.  Calculate the extent of the reaction.
