The article examines the problems of disposal of industrial gases containing sulfur dioxide, which
are produced during the production of non-ferrous metals such as copper and zinc. In order to completely
dispose of industrial gases containing sulfur dioxide, a method of absorption in lime suspension was
proposed, and the kinetics and thermodynamic possibilities of the process were studied. The result of
thermodynamic calculations showed that among the chemical reactions that flow in the gas and solution
system, the reaction of sulfuric acid with calcium carbonate is the slowest (limiting) step for the overall
process, and 60 oC is the optimal temperature for the process. installed.
