Fresh feed consisting of equimolar amounts of species A and B is mixed with a recycle stream consisting of species A and D. The mixed stream enters a heated reactor in which the following reactions occur: A+BB+BA+DC with stoichiometric coefficients in moles and time in hours. All of the B is consumed in the reactor and the ratio of the extents of reactions (1) and (2) is equal to the ratio of the moles of A and B fed to the reactor. The output from the reactor is fed to a still in which all of the C is removed as bottoms product and a mixture of A and D emerging as distillate is split to form a recycle stream and a purge stream. The recycle stream is mixed with the aforementioned feed. The total fresh feed to the process is 100.0mol/h of which 50.0mol% is A. The still produces 42.5mol/hofC. From balances on the overall system and the reaction stoichiometry calculate the following quantities. Molar flow rate of A Molar flow rate of in the fresh feed: mol/h the purge stream: mol/h1 = Molar flow rate of B Molar flow rate of in the fresh feed: mol/h the purge stream: mol/h2 Molar flow rate of C in the bottoms mol/h product: Recycle and Reactor Feed What is the ratio of A to D in the recycle stream? What is the ratio of A to B in the reactor feed? Reactor Feed and Recycle/Purge Ratio Calculate the following quantities. Molar flow rate of A into the reactor: Molar flow rate of B into the reactor: mol/hmol/hMolarflowrateofAintherecyclestream:MolarflowrateofDintherecyclestream:mol/h Molar flow rate of D into the mol/h Ratio of the molar flow rate of recycle reactor: to purge: Attempts: 0 of 3 used Recycle Ratio for Another Case If the production of C were 41.25mol/h, what would the recycle-to-purge ratio be?
