Question: A dry gas containing 10.0% NH 3 by volume is contacted with water at 10C and 1 atm in a single-stage bubble contactor. The effluent
A dry gas containing 10.0% NH3 by volume is contacted with water at 10°C and 1 atm in a single-stage bubble contactor. The effluent liquid and gas streams may be considered to be in equilibrium with each other. A small slip stream taken from the effluent liquid is fed to a continuous densitometer, which indicates that the liquid density is 0.9534g/mL.
(a) Using tabulated data from Perry’s Chemical Engineers’ Handbook (pp. 2-85, 2-87, and 299),11 estimate the percentage of the ammonia in the feed that is removed in the contactor.
(b) Why is it important to maintain the slip stream and densitometer chamber at a known temperature at or below the temperature of the contactor?
