  • Working Paper: Benefits and Costs from Sulfur Dioxide

    Dec 05, 2014We examine data on the 148 coal-fired utilities which were regulated under Title IV and find as expected that the monetary benefits of reduced SO2 emissions under Title IV greatly outweigh the costs: we estimate benefits of nearly $56 billion and costs of just $558 million.

  • SO2 (Sulfur Dioxide) Air | SGS

    The SO 2 air process is relatively simple and invariably cost-effective. During the process, sulfite ions react with atmospheric oxygen and a copper catalyst as follows: 2CN- + Na 2 S 2 O 5 + 2O 2 + 2OH- -- 2CNO- + Na 2 SO 4 + SO 4 2-+ H 2 O. The SO 2 process offers a number of advantages over other cyanide destruction methods including:

    Apr 02, 2018Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain.
