Ammonia gas is being absorbed by water in a wetted-wall column. At one level of the column, the following data applies:
gas-phase mass transfer coefficient 5.22 × 10–9 kmol m–2 s–1 Pa–1
liquid-phase mass transfer coefficient 3.88 × 10–5 m s–1
Henry's constant 0.955 kPa (kmol m–3)–1. mole fraction of ammonia in liquid* 1.351 × 10–3 mole fraction of ammonia in gas* 0.065
total pressure of system 1.013 bar
mole mass of ammonia 17
*Note: these values will need to be converted to concentrations in kmol m–3.

(a) What is the partial pressure of the ammonia gas at the gas/liquid interface?

(b) What is the molar concentration of the ammonia in the liquid at the interface?

A waste gas stream containing 5.5% ammonia in air is being stripped of the bulk of the ammonia by absorbing it in water in a tray tower. The liquid to gas ratio on a molal basis is known to be 2.5. Both the inlet gas and inlet water streams enter at 25oC. The inlet and outlet gas streams may be assumed to be saturated with water vapour. During operation a thermocouple in the outlet liquid stream measures a temperature of...

A 2-in-ID wetted wall column is being used to strip CO2 from an aqueous solution by an air stream at 1.0 m/s. At one point in the column, the concentration of CO2 in the air stream is 1.5 mole percent. At the same point in the column, the concentration of CO2 in the water is 0.5 mole percent. Determine the gas-mass-transfer coefficient kG (kg mole/atm-m2-s) and the mass flux at the point in the column. The column is operated at...

A body of water is being retained by a concrete dam wall (15 ft high and 6 ft thick). What is the maximum height the water can rise without causing the intensity of pressure at the toe greater than twice the average pressure on the base? Assume that concrete weighs 150 lbs per cubic foot, there is no seepage causing uplift against the bottom of the wall, and water weighs 62.5 lbs per cubic foot.
