Gas Film Coefficient of Mass Transfer in Packed Bede at Low Reynolda Numbers

Abstract

Gas film coefficients of mass transfer are measured for packed beds by using a pulse reactor method. Axial dispersion of fluid is taken into consideration to analyse experimental results.
Mass transfer coefficients for absorption of gaseous CO₂ into concentrated aqueous KOH film supported on spherical packings are approximately expressed by Sh (koo dp/Dm) =10-12 for the flow region of Re Sc^2/3<50
