A gas contains 30% HCl and 70% air by volume. The gas enters an absorption tower at 120°F and 743 mmHg. Suppose that 96% of the HCl is removed in the column and that the gas leaves at 75°F, 740 mmHg. Calculate: a. the pounds of HCl removed per 100 ft 3 of entering gas b. the composition in %v of the exit gases c. the average molecular weight of the entering gas (MW: Cl =35.45, air = 29) Note: make a diagram of the process

Question
A gas contains 30% HCl and 70% air by volume. The gas enters an absorption tower at 120°F and
743 mmHg. Suppose that 96% of the HCl is removed in the column and that the gas leaves at
75°F, 740 mmHg. Calculate:
a. the pounds of HCl removed per 100 ft 3 of entering gas
b. the composition in %v of the exit gases
c. the average molecular weight of the entering gas
(MW: Cl =35.45, air = 29)
Note: make a diagram of the process
