CaCO3, 50% water, 5% inert). The analysis of the flue gas leaving the cold end of the kiln is 20% CO2, 1% CO, 76%N, and 3% O2. Methane at the rate of 30,000ft³/hr (measured dry at 60°F and 1atm) is used to fire the kiln. If the lime conversion is 90% complete, how many lbs per hour of lime in produced?

J 5
67 A kiln is operated countercurrently to produce lime by burning calcium carbonate
sludge (45%
CaCO3, 50% water, 5% inert). The analysis of the flue gas leaving the cold end of the kiln
is 20%CO2, 1% CO, 76%N, and 3% O2. Methane at the rate of 30,000ft3/hr (measured dry
at 60°F and 1atm) is used to fire the kiln. If the lime conversion is 90% complete, how
many lbs per hour of lime in produced?
a. 108.5
b. 6076
c. 1052
d. 374.5
