Experimental results on absorption of CO2 in liquid film flowing downwards the string of spheres are presented for liquids with viscosities in the range from 1 to 10.1 mPa s. The results correspond qualitatively to the Levich's analysis of mass transfer into the flowing film with wavy surface. Equation relating dimensionless numbers is proposed for calculation of the volumetric mass transfer coefficient.
