Data on the kinetics of mass transfer in absorption of sulfur dioxide in vessels with a moving bed of bead packing and in nonpacked spray absorbers have shown that an important parameter affecting the efficiency of gas purification is the ratio between the partial pressure of SO/sub 2/ in the gas being purified and the concentration of components that are chemically active with respect to SO/sub 2/, i.e., the reactivity of the absorbent. With an instantaneous bimolecular reaction in the liquid phase between the reactive components and SO/sub 2/, the effective mass transfer coefficient in the liquid phase in the absorption of SO/sub 2/ can be expressed on the basis of penetration theory. Values of the mass transfer coefficients in the gas and liquid phases for the absorbers they are considering here have been calculated for treatment of stack gas in power generating stations to remove sulfur dioxide in experimental commercial units.
