Rezumat: The most widely used process for purification of flue gases from SO2 is its absorption with slurry containing CaCO3. Up to now there are installations for carrying out of the SO2 absorption according to this process only for big capacity boilers because of the great height of the existing absorbers for this technology, about 20-30 m. To create new absorbers for small and middle capacity boilers, equilibrium data for the absorption of SO2 are necessary. Up to now such data are available in the o literature only for a temperature of 25 C. That is why experiments for obtaining of equilibrium data for the partial pressure of SO2 over slurry containing CaCO3, CaSO3 and CaSO4 at different o temperatures are carried out. The results show that the increasing of the temperature from 25 to 45 C leads to about 3 times increasing of the partial pressure of SO2 in the area of the lowest partial o o pressures. The respective increasing for the range of 25 to 60 C is about 10 times.
