Abstract |
The report presents results of a laboratory study on production of hydrogen sulfide by reaction between water vapor at 700-800C and iron sulfide contained in neutral-roasted pyritic copper ore concentrate. Hydrogen sulfide thus obtained was to be reacted with sulfur dioxide emitted from copper smelter converters. In this manner sulfur emissions from a smelter could be controlled and recovered in the form of elemental sulfur. It was determined that the above treatment of copper ore concentrate could yield necessary quantities of hydrogen sulfide. The concentration of yielded hydrogen sulfide, however, was limited in the stream to less than 1.0 percent by reaction equilibrium conditions, thus implying excessively high energy requirements and causing this control approach to be significantly more expensive than known conventional processes. Alternative means of hydrogen sulfide production are dealt with in the second volume of the report. |
