The report gives results of an engineering analysis of the applicability of molecular sieve technology to the control of SO2 emissions from sulfuric acid plants. After the equivalent of 10 months of operation, one plant using this technology is still controlling SO2 emissions to well within Federal and State regulations for sulfuric acid plants. It is also meeting the performance guarantee of the process developer and vendor. Although the concept of a 2-year sieve life with acceptable SO2 control has not been demonstrated, there is no reason to believe that it cannot be achieved: at this point this application of molecular sieve technology appears technically feasible. The economic feasibility of the technology for this application was assessed by comparing its total capitalized cost (including investment and operating cost) with that of the Wellman-Lord and dual absorption processes. Capitalized costs for the three are fairly close; individual plant characteristics will affect the economic choice. The technology is more competitive for smaller plants and for those which already have sieve-regeneration air driers. Although the dual absorption process will be the least expensive for many plants, it is limited in its effectiveness. Considering overall cost and effectiveness, molecular sieve technology appears to be economically feasible for some acid plants.
