Example Problem
A dry air stream at 5 bar enters a single-stage stripping process and is contacted with water that contains an organic compound at 20°C. The Henry’s coefficient for the organic is 2.5 bar. What flow rate of air per mole of water is needed to reduce the amount of organic in the water by 95% if the concentration in the entering liquid phase is 0.05%?
