Flowsheets acidmaking

Fig. 19.2. Double contact acidmaking flowsheet with numerical values used in this chapter s calculations. The plant consists of 3 catalyst beds followed by intermediate H2S04 making and a 4th catalyst bed. The gas from the last catalyst bed goes to cooling and final H2S04 making (not shown). All kg-mole values are per kg-mole of 1st catalyst bed feed gas. Gas pressure = 1.2 bar, all beds.

Figure 23.1 is a simplified sulfuric acidmaking flowsheet. Its inputs are...
