| Abstract: | With consideration to cost effectiveness and reducing consumption,this article outlines the revamp measures in the baking,purification and dry absorption sections for the expansion and revamp of the 40 kt/a pyrite-based sulfuric acid plant using single-conversion and single-absorption process to the 80 kt/a plant using double-conversion and double-absorption process,which has achieved closed circulation of diluted acid,zero sewage discharge and offgas vent conforming to the standard. |
