For a temperature of 60C and a permeate pressure of 15.2 mmHg, Wesslein et al. [45] measured
Question:
For a temperature of 60°C and a permeate pressure of 15.2 mmHg, Wesslein et al. [45] measured a total permeation flux of 1.6 kg/m2-h for a 17.0 wt% ethanol in water feed, giving a permeate of 12 wt% ethanol. Otherwise, conditions were those of Example 14.12. Calculate the permeances of ethyl alcohol and water for these conditions. Also, calculate the selectivity for water.
