Economical abatement of high-strength SO_2 off-gas from a smelter

摘要

With increasing use of oxygen enrichment and advances in smelting technology, SO_2 concentrations in smelter off-gases are increasing, which necessitates larger acid plant equipment and increases in capital and operating. To counteract the shortcomings in conventional acid plants, Chemetics provides two unique solutions: the Chemetics High Strength (CHS~(TM)) process and the Chemetics Pseudo-Isothermal process utilizing the CORE? reactor technology. In this paper we present a general outline of these two solutions and how they can be implemented in new or existing acid plants.
