A dilute solution of solute A in solvent B passes through a tubular-membrane separator, where feed flows through the tubes. At a certain location, the solute concentration are 4.5x10-2 and 1.2x10-2 kmol/m3, respectively on the feed and permeate sides. The permeance of the membrane for solute A is 7.2x10-5 m/s. If the tube side Reynolds number is 15,000, the feed Schmidt number is 500, the diffusivity of the feed-side solute is 6.35x10-5 cm2/s and the internal diameter of the tube...
2. At any location in a dialysis membrane of thickness 2.5 x105 m, the value of Kim is 0.85 for a solute i. The value of the feed (blood) side mass transfer coefficient for the solute at that location, kir, is 4.6x 105 m/s; the corresponding value on the dialysate side is kip 2.6x10 m/s. The effective diffusion coefficient of the solute in the membrane is 4x1011 m2/s (this incorporates the membrane porosity and tortuosity factors). The feed liquid concentration...
Design a single stage RO desalination system by calculating the permeate salinity, the brine salinity, the brine flow rate, and the membrane area. Analyze the following cases:DataWater permeability is \(2.05 \times 10-6 \mathrm{~m} 3 / \mathrm{m} 2 \mathrm{~s} \mathrm{kPa}\)Salt permeability is \(2.03 \times 10-5 \mathrm{~m} 3 / \mathrm{m} 2 \mathrm{~s}\)Feed salinity is 34,000 ppm Feed flow rate: \(2.5 \mathrm{~kg} / \mathrm{s}\) Permeate flow rate: \(1 \mathrm{~kg} / \mathrm{s}\) Feed pressure: \(6000 \mathrm{kPa}\) Reject pressure: \(5800 \mathrm{kPa}\) Permeate pressure: \(101 \mathrm{kPa}\)
A membrane process is being designed to recover solute A by dialysis through a membrane. The solute moves from a dilute feed solution (c1 =5 x 10-2 kg mol A/m3) to a fresh dialysate (permeate) solution (c2 = 0.3 x 10-2). The membrane thickness is 30 µm. You also need to know that the distribution coefficient is K’ = 0.75, Ds = 3.5 x 10-11 m2/s in the membrane, the mass-transfer coefficient in the dilute solution is kc1 = 2.5...
