Abstract |
In the abatement of air pollution from industrial sources large quantities of sulfuric acid are produced. The growing oversupply of world sulfur promises uncertainty of future markets for such acid. From an earlier study, it appears that the neutralization of abatement derived sulfuric acid with limestone may be an economically and technically feasible answer to the problem of acid disposal when acid markets are not available. This report includes a pertinent literature search, conceptual design, and flow sheet for the neutralization of abatement derived sulfuric acid with limestone. Investment and operating costs are developed for daily H2SO4 capacities of 100 tons, 350 tons and 1000 tons. The results of pertinent laboratory experimentation by American Smelting and Refining Company are also discussed. |
