Determine the tower height required to remove 90% of CO2 from air by water in a dilute solution in a packed tower with a 1.5 in metal Pall rings at T=303 k and P=101.32 kPa. The flowrates are Gx=4.069 kg/s*m^2 (3000 lbm/h*ft^2) and Gy=0.5424 kg/s*m^2 (400 lbm/h*ft^2). The feed stream contains 1% CO2 mol, give answers in feet. Redo for removals between 85% and 99%. Redo for air temperature of 20 C and 25 C. Plot tower height Vs removal with air temperature as a parameter.
For CO2 pa=1.86*10^3xA ya=pA/1=1.86*10^3xA viscosity of air =1.866*10^-5 kg/m*s and density=1.166 kg/m^3. The diffusitivity for CO2 at 276.2 K is 0.167*10^-4 m^2/s. Nsc=0.958.
