Problem 6.3: (46 marks) Feed mixture contains 5 mol% propane and 95 mol% propylene (CzH.), is used to produce butanal (C4H:O) according to the following reaction: - CH, + CO + H2 C4H8O An overall CzH conversion of 0.9 can be achieved. Propane is an inert and therefore, a purge stream is installed to avoid accumulation of propane in the process. The single-pass conversion of propylene in the reactor is 0.3. The butanal production rate is maintained rate of 180 kmol/h. Unreacted hydrogen and carbon dioxide is separated and sent to surge tanks (stream 6). a) Find the NDF for each control volume (16 marks) b) Calculate the flow rate of the fresh propane/propylene stream to the process (kmol/h), the mole percentage of inert in the purge stream, and the total flow rate (kmol/h) of the feed to the reactor. (10 marks each=30 marks)
