Calculation of catalytic reactors

Unit type: double absorption (2 + 2). Sulfur combustion with air injection cooling between 3rd and 4th bed.

a = 12% by volume of SO ₂ in the gas.

b = 9% by volume of O ₂ in the gas.

x (%) is the conversion rate.

Production: 300 t/d of 100% sulfuric acid.

Overall efficiency: 99.3%.

Gas composition at the converter inlet is as follows:

• SO ₂ ...
