dc.description.abstractInvestigations are reviewed on development of energy efficient technology for SO2 removal from flue gases of combustion systems by using the method of Wellman-Lord. This method is characterized by absorption of sulfur dioxide with sodium sulfite solution, which reacts to form sodium bisulfite. The absorber is typically a packed column with multiple stages. After evaporation of the solution, SO2 and sodium sulfite are obtained. The latter is dissolved in water from condensation of the steam carrying SO2 from the evaporator. The regenerated solution returns in the absorber. The SO2 removed from the flue gases is obtained as a pure product for use in chemical, food or wine production. Technical and economical assessment of this regenerative method is presented in comparison to the non-regenerative gypsum method, using data from the existing research papers and own experience from investigations on improvement of the Wellman-Lord method and development of innovative gypsum technology.
