Gaseous ammonia (NH3) at 10°C is fed at a rate of 9 kg/min to a blending unit where it is mixed with hot air. The resulting air-NH3 mixture has an O2:NH3 molar ratio of 2:1 and is at 600°C. The blending unit is not well insulated, and loses heat to the environment at a rate of 500 kJ/min. Calculate the temperature of the hot air entering the blending unit.Gaseous ammonia (NH3) at 10°C is fed at a rate of 9 kg/min to a blending unit where it is mixed with hot air.

In the manufacture of nitric acid, ammonia and preheated air are mixed to form a gas containing 10 mole% NH3 at 600oC. (The ammonia is not preheated, since if it were, it will decompose to N2 and H2). The mixture is then catalytically oxidized to form NO2, which is absorbed in water to form HNO3. If ammonia enters the gas blending (mixing) unit at 25oC at a rate of 520 kg/h, and heat is lost from the mixer to its...
