One method of producing propylene is the dehydrogenation of propane (C3H8) to propylene (C3H6) according to the reaction: C3H8C3H6+H2 A schematic of the reaction is shown below. The fresh feed (Stream 1 ) has a total flow rate of 100.mol/min and is composed of 96mol% propane and 4.0mol% propylene. The single pass conversion of propane across the reactor is 40% and all of the hydrogen is separated in the flash drum. Stream 5 exiting the flash drum is fed to a distillation column where 90% of the propylene is separated. The product (Stream 6) exiting the distillation column is composed of 99mol% propylene and 1.0mol% propane. The second stream exiting the column (Stream 7) is recycled back into the process. a) Why is there no purge stream for this process? (5 points) \{no impurities or excess reactants? b) What is the overall conversion of propane? (15 pts) {99%} c) What is the molar flow rate of propane in Stream 2 ? (10 pts) {238mol/min} d) What is the molar flow rate of propylene in Stream 7 ? (10 pts) {11mol/min} e) What is the recycle to fresh feed ratio (Stream 7/ Stream 1) ? (15pts) {1.5} f) Suggest 2 possible reasons why the single pass conversion of propane is relatively low. (5 points) \{slow kinetics, reaction reaches equilibrium\}
