A pervaporation system will be used to remove water from n-butanol using a cellu- lose 25-acetate membrane in a perfectly mixed module. Feed is 90.0 mol% n-butanol. Feed rate is 100.0 lb/h. Flux is 0.2 lb/ft2h. Pervaporation unit operates at TP-T- 30.0°C where selectivity of water compared to butanol is 43.0 (in mole fraction units. WATCH UNITS!). Data: Latent heats: butanol = 141.6 cal/g: water = 9.72 kcal/gmol. Cp.B (45.0°C) = 0.635 cal/g oC. Cp,w (45.0°C) = 1.0 cal/g oC. MWB = 74.12. MW- 18.016. Assume heat capacities and latent heats are independent of temperature. a. If feed is at 60.0°C, find cut, permeate mole fraction, outlet liquid mole fraction, and membrane area. and feed inlet temperature. inlet feed temperature. b. If cut ? = 0.08 is used, find permeate mole fraction, outlet liquid mole fraction, c. If outlet water liquid mole fraction is 0.05, find permeate mole fraction, cut, and
