The gas leaving an ammonia oxidation plant consists of: 10% nitric oxide (NO),1% nitrogen oxide (NO2),8% oxygen. The gas is allowed to oxidize (NONO2) until the NO2:NO ratio reaches 8:1. The oxidized gas is then absorbed in water to produce nitric acid. (3NO2+H2O2HNO3+NO). Calculate the size of tubular reactor (assume plug flow) operating at 20C and 1atm needed for this oxidation for a gas feed rate of 10,000m3/hr (measured at 0C and 1atm ). According to Bodenstein in Z. Phys. Chem. 10087 (1922) the reaction proceeds at 20C as follows: 2NO+O22NO2rNO2=14,000C2NOCo2[kmloe/m3sec]
