Abstract :
Thermal power plants play a major role in the production of air pollutants, with significant consumption of fossil fuels. Sulfur oxides are among these pollutants.So far, none of Iran's thermal power plants have been equipped with technologies to reduce and control sulfur oxide emissions. Due to the necessity of reducing pollutants caused by fuel combustion in power plants of the country, and imposing high social costs due to the excessive emission of pollutants,This paper seeks to play an effective role in managing the emission of this pollutant by presenting a strategy to prioritize and select sulfur oxide-lowering technology with an investment approach in Iranian thermal power plants. . In this study, fuzzy Delphi technique was used to select the criteria for effective investment in technology and Simultaneous evaluation of criteria and alternatives (SECA)was used to rank SOx-lowering technologies. The results showed that dry scrubber technologies, regenerable process, corona discharge, sorbent injection process and absorption technology were the first to fifth priority of of technology selection, respectively.
