65046 Consider a membrane based gas separation process with one input and two output streams. The input feed stream consist of a gas mixture with Oz (21 mol %) and N2 (79 mol %). The permeate (product-1) stream consist of 30 mol% O2 and 70 mol % Ny and the rest goes to the retentate stream (product-2). Also, it is given that the retentate (product-2) flow rate is 80% of the feed flow rate Present the following information based on the flowrate of the input feed stream = 100 mol/s. [2+2+2+2 = 8 Marks] a Draw a labeled flow sheet showing all the flow streams. b. Conduct a degree of freedom analysis indicating all the equations and variables accounted for in the calculation C. Flowrate of the permeate stream (product-1). d. Determine the composition of the retentate stream (product-2)
