the paper proposes an adsorption-based method of how to remove sulfur dioxide from the gas emissions produced by industrial companies. A power plant waste – chemical water treatment sludge from Kazan CHPP-1 – was used as an adsorption material. The authors refere here to the chemical composition of the sludge and describe the method of its modification. A new sorption material based on power plant waste was tested for removal sulfur dioxide from the gases. This was resulted in kinetic dependence and adsorption isotherm. The mechanism of how the sulfur dioxide can be adsorbed by a new sorption material at different temperatures was studied. The tests revealed Gibbs free energy, differential heat, and adsorption activation energy. The economic and environmental effect of upgrading the process of removal of sulfur dioxide from gas emissions was calculated for the sodium bisulfite production line of L. Ya.
