8.15. Five moles of gas consisting of @Cl2 = 0.400; QHCI = 0.200; psiCl. = 0.100; PSIHCl3 = 0.300 are initially at 800 K. Five moles of N, initially at 300 K are mixed with the gas under adiabatic conditions. Calculate the resulting gas temperature accurately. 8.16. A spent iron ore reduction gas has the following composition: PCO-0.18: CO - 0.21; pll2 = 0.31; balance H2O The gas enters a spray quench tower at 550 C, where water at 5C is used to cool and eventually dehumidify) it. Gas volumes are actual. Make a system balance for the cooling process to calculate the actual m of gas leaving the cooler, starting at an exit temperature of 450 C and thereafter at 50 temperature intervals down to the dew point. Continue the material and heat balance calculations at 10 C intervals from the dew point to 20 C, calculating the mass of water and actual m' of gas leaving the quench tower. The stack gas (and water, if any) leave the tower at the same temperature. P - 2 bar. Neglect heat loss. Water (5 C) Stack gas (100 m/sec, 2 bar, 550 C) Quench tower Stack gas Water
