Abstract

The theoretical analysis (see Chap. 4) of the method and apparatus for waste gases purification from SO2 using two-phase absorbent (CaCO3 suspension), which are applied by some companies (Babcock & Wilcox Power Generation Group, Inc., Alstom Power Italy, Idreco-Insigma-Consortium) in the thermal power plants shows that the interphase mass transfer process in the system gas-liquid drops is practically physical absorption as a result of the low concentration of the dissolved SO2 and CaCO3 in the water and the short reaction time (short existence of the absorbent drops). It was shown that in these conditions the interphase mass transfer resistances in both phases are commensurate (44.4 % in the gas phase and 55.6 % in the liquid phase), but the possibility for intensification of the mass transfer in the liquid phase is very limited.
