Q3) Pulverized coal pellets, which may be approximated as carbon spheres of radius R = 1.5 mm, are burned in a pure oxygen atmosphere at 1400K and 1.2 atm. Oxygen is transferred to the particle surface by diffusion, where it is consumed in the reaction, C(s) + O2(g) → CO2(g). The reaction rate is first order and of the form R = -k.Co2 at r = R where k = 0.12 m/s. This is the reaction rate per unit surface area of the carbon pellets. Neglecting change in R, determine the steady-state O2 molar consumption rate in mol/s. At 1400K, the binary diffusion coeffici for O2 and CO2 is 1.6x104 m2/s.

Date: 1 of 1 PROBLEM 6.18 Air at 90°C and 1.00 atm (absolute) contains 10.0 mole% water. A continuous stream of this air enters a compressor-condenser, in which the temperature is lowered to 15.6°C and the pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to 100°C. Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°C, and the ratio m outlet air @ 100°C /m feed air @ 90°C. Solution Basis: 1 mol feed. Since the problem statement asks us to calculate the ratio of the volumes of feed air and exit air, we will label both volumes on the flowchart.

Show the process-flow diagram Blue water gas (BWG) is obtained by passing steam over red hot carbon-enriched coal. The gas is called "blue" water gas due to the blue flame associated with the process, a characteristic of the combustion of CO. A typical composition shows 4.9% CO2, 40.8% CO, 49% H2, 0.9% CH4, and 4.4% N2. Blue water gas at 23°C, 748 mmHg, and 90% RH is burned in wet air, supplied 30% in excess at the same conditions as the blue water gas at 85% RH. The molar ratio of CO, to CO in the flue gas is 1:8.
