Two-hundred fifty pounds per hour of iron pyrites containing 90% FeS2 and 10% gangue are burned with 20% excess air based on conversion to SO3. The cinder discharged from the burner contains no sulfur. No conversion to SO3 occurs in the burner. The burner gas is passed through a converter which effects a 98% conversion of SO2 to SO3. The converter gas is passed to an absorber where all the SO3 is absorbed by 80% H2SO4 solution, which becomes 100% H2SO4 solution in the process. Establish a basis of one hundred pounds of iron pyrites Calculate: (a) the burner gas analysis, (b) the converter gas analysis, (c) pounds of 100% H2SO4 produced per 24-h day, if waste gas analyzes 0.19% SO2, 4.14% O2 and 95.67% N2

Question

Two-hundred fifty pounds per hour of iron pyrites containing 90% FeS2 and 10% gangue are burned with 20% excess air based on conversion to SO3. The cinder discharged from the burner contains no sulfur. No conversion to SO3 occurs in the burner. The burner gas is passed through a converter which effects a 98% conversion of SO2 to SO3. The converter gas is passed to an absorber where all the SO3 is absorbed by 80% H2SO4 solution, which becomes 100% H2SO4 solution in the process.

Establish a basis of one hundred pounds of iron pyrites

Calculate:

(a) the burner gas analysis,

(b) the converter gas analysis,

(c) pounds of 100% H2SO4 produced per 24-h day, if waste gas analyzes 0.19% SO2, 4.14% O2 and 95.67% N2
