2. A perfectly mixed gas permeation module is separating carbon dioxide from nitrogen using a poly(2,6-dimethylphenylene oxide) membrane. The feed is 25.0 mol% carbon dioxide and is entering the modulde at 25C at a feed rate of 10.0 mol/min. The module is operated with a retentate pressure of 5.9 atm and a permeate pressure of 1.01 atm. We desire a permeate that is 40.0 mol% carbon dioxide. The membrane thickness is 1.0 x 104 cm. Permeabilities are given in Tab. 2. Calculate the permeate flow rate (in mole/min), the cut, and the required membrane area. Table 2: Permeabilities at 25C CO2 5.70 x 10-7 cm (STP) cm/[cm2 s atm] N2 3.37 x 10-8 cm (STP) cm/[cm2 s atm]
