QUESTION 3 Membrane separation is very effective to separate components that are suspended or dissolved in a liquid. The solutes molecules must first be transported or diffuse through the liquid film of the first liquid phase on one side of the membrane, then through the membrane itself, finally through the film of the second liquid phase. A liquid containing dilute solute Z at a concentration C1 = 3.2 x 102 kg mol/mis flowing rapidly pass through a membrane with thickness, 3.3 x 10-5 m. The distribution coefficient, 1.6 and diffusivity of Z is 7.2 X 10-11 m/s in the membrane. The solute diffuses through the membrane, and its concentration on the other side is c2 = 0.52 x 10-2 kg mol/m? The mass transfer coefficient ka is half of mass transfer coefficient of kcz. ke2 = 2.02 x 10 m/s. a) Classify five (5) main types of membrane separation process (5 marks) b) Derive steady-state flux equation (6 marks) c) Calculate the flux.
