Third catalyst bed SO2 oxidation

SO2 oxidation in three catalyst beds with gas cooling between beds then  

H2SO4 making by contact of cooled third catalyst bed exit gas with strong sulfuric acid (Fig. 16.1). 

This chapter describes cooling of second catalyst bed exit gas and oxidation of the cooled gas SO2 in a third catalyst bed. Its objectives are to
