Question

A packed absorption tower operates at an average absorption factor of 1.35. The liquid flow rate is 65 kmol/(m^2)(hr) and the equilibrium relation is y = 1.5x. The overall gas-phase mass transfer coefficient is KGa = 0.0113 kmol/(bar)(sec)(m^3) and the total pressure is 1.05 bar. Calculate the HETP of the packing (in meters) if the feed gas is dilute. Interpret the result on the goodness of the packing material used.

Step 1

Assuming the liquid density is 1000 kg/m3 and the void fraction is 0.4 (typical for packed columns), we get: kya = 0.0113 / (1000 * (1 - 0.4)) = 0.0188 kmol/(m2)(s)(bar) Show more…
