Three-catalyst-bed converter calculations

All calculations in this appendix are per kg mol of first catalyst bed feed gas. They are based on the specifications in Table 18.1. 

This appendix shows how three-catalyst-bed converter calculations are done. Three areas in the same Excel worksheet are used (Tables S. 1, S.2, S.3). The three beds are linked by kg mol SO3, SO2,02, N2, and CO2 passing between beds 1 and 2 and beds 2 and 3. 

Each area is arranged so that the same cells in all three areas have the same meaning. For example, cells K6, AK6, and BK6 all contain catalyst bed pressure. 

The objectives of the three-bed calculations are to determine, for any set of Table 18.1 specifications
