Question

A process gas containing 4% chlorine (average molecular weight 30) Is being scrubbed at a rate of 14 kg/min in a 13.2-m packed tower 60 cm in diameter with aqueous sodium carbonate at 850 kg/min. Ninety-four percent of the chlorine is removed. The Henry's law constant (y_Cl2/x_Cl2) for this case is 94; the temperature is a constant 10 degree C, and the packing has a surface area of 82 m^2/m^3. Find the overall mass transfer coefficient K_G. Assume that this coefficient results from two thin films of equal thickness, one on the gas side and one on the liquid. Assuming that the diffusion coefficients in the gas and in the liquid are 0.1 cm^2/sec and 10^-5 cm^2/sec, respectively, find this thickness, Which phase controls mass transfer?
