You will remove carbon dioxide from air using membrane. For this problem a feed-mixture of air with mole fractions of 0.07 dry air, with mole fractions of 0.70 dry air, 0.20 carbon dioxide enters into a membrane separation unit. Ninety percent of the entering carbon dioxide exists in the permeate the mole air exits in the permeate for every 5 moles carbon dioxide in the permeate. The remaining air,and carbon dioxide exit in the retained stream. You are to design a process to produce 1000 m3/hr of product gas (purified air). a) Draw and label a PFD, or label the one provided, including units with all relevant variables. (b) Label a basis of calculation (c) Calculate the molar flow rates of all components in each stream, according to the basis used. (d) Calculate the mole fractions of component in the product stream. Calculate the average molecular weight of the product stream. (e) Scale as necessary to determine the amount of incoming feed necessary
