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 concentration on the feed and permeate sides are 5x 10-2 kmol/m3 and 1.5x 10-2 kmol/m3 , respectively. The permeance of the membrane for solute A is given by the membrane vendor as 7.3x 10-4 m/s. If the tube side Reynolds number is 15,000, the feed-side solute Schmidt number is 500, the diffusivity of the feed-side solute is 6.5 x 10-5 cm2 /s, and the inside diameter of the tube is 0.5 cm, estimate the solute flux through the membrane if the mass-transfer resistance on the permeate side of the membrane is negligible.

100%
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 concentration on the feed and permeate sides
are 5x 10-2 kmol/m3 and 1.5x 10-2 kmol/m3
, respectively. The permeance of the membrane for solute A is
given by the membrane vendor as 7.3x 10-4 m/s. If the tube side Reynolds number is 15,000, the feed-side
solute Schmidt number is 500, the diffusivity of the feed-side solute is 6.5 x 10-5 cm2
/s, and the inside
diameter of the tube is 0.5 cm, estimate the solute flux through the membrane if the mass-transfer
resistance on the permeate side of the membrane is negligible.
