Example 15-3 Reducing Nitrous Oxides in a Plant's Effluent In Section 7.1.4 we saw that Nitric Oxide (NO) plays an important role in smog formation and there are great incentives for reducing its concentration in the atmosphere. It is proposed to reduce the concentration of NO in an effluent stream from a plant by passing it through a packed bed of spherical, porous carbonaceous solid pellets. A 2%NO and 98% air mixture flows at a rate of 1106m3/s(0.001dm3/s) through a 2-in.-ID tube packed with porous solid pellets at a temperature of 1173K and a pressure of 101.3kPa. The reaction NO+CCO+21N2
