A dilute solution of solute A in solvent B is passed through a tubular-membrane separator, where the feed flows through the tubes. At a certain location, solute concentrations on the feed and permeate sides are 5.0x10-2 kmol/m3 and 1.5x10-2 kmol/m3.The permeance of the membrane for solute A is given by the membrane vendor as 7.3 x 10-5 m/s. If the tube-side Reynolds number is 25,000, the feed-side solute Schmidt number is 500, the diffusivity of the feed-side solute is 6.5x 10-5 cm2/s, and the insidediameter of the tube is 0.4 cm permeateside mass-transfer coefficient = 0.06 cm/s., estimate the solute flux through the membrane if the mass-transfer resistance on the permeate side of the membrane is negligible.

Question

A dilute solution of solute A in solvent B is passed through a tubular-membrane separator, where the feed flows through the tubes. At a certain location, solute concentrations on the feed and permeate sides are 5.0x10-2 kmol/m3 and 1.5x10-2 kmol/m3.The permeance of the membrane for solute A is given by the membrane vendor as 7.3 x 10-5 m/s. If the tube-side Reynolds number is 25,000, the feed-side solute Schmidt number is 500, the diffusivity of the feed-side solute is 6.5x 10-5 cm2/s, and the inside
diameter of the tube is 0.4 cm permeateside mass-transfer coefficient = 0.06 cm/s., estimate the solute flux through the membrane if the mass-transfer resistance on the permeate side of the membrane is negligible.
