A tower packed with 1 inch (25 mm) metal Hiflow rings is to be built to treat 25,000 (30) ft3 of entering gas per hour. The ammonia content of the entering air is 3% byvolume. Ammonia-free water is used as absorbent. The temperature is 68oF andthe pressure is 1 atm. The ratio of gas flow to liquid flow is 0.1 lb of gas per lb of liquid. (a) If the gas velocity is to be half of the flooding velocity, what should be the diameter of the tower? (b) What is the pressure drop if the packed section is 20ft high?

Question
A tower packed with 1 inch (25 mm) metal Hiflow rings is to be built to treat 25,000 (30) ft3 of entering gas per hour. The ammonia content of the entering air is 3% by
volume. Ammonia-free water is used as absorbent. The temperature is 68oF and
the pressure is 1 atm. The ratio of gas flow to liquid flow is 0.1 lb of gas per lb of liquid.
