2. A product is synthesized from reactants A and B by the reaction 5A+38 40 In the following continuous, steady-state process shown in the following Figure, a gaseous fresh feed (Feed) containing A, B and inert impurities is mixed with a gaseous recycle stream, which also contains A, B and inert impurities. The mixed stream then enters the reactor. The reactor effluent flows to a separator where all the product is condensed off as a pure product stream. The gases leaving the separator (A, B, inert impurities) are separated into two streams. One is ejected from the system as a purge stream. The second is recycled and mixed with the fresh feed. A, B, C inert impur- ities Separator Product Reactor Feed A, B, inert impurites Recycle Purgo A B, inert A, B, inert impurites impurites a. The molar flowrate of C in the product stream is 760 kmol/hr. The molar flowrate of A in the fresh feed into the system is 1000 kmol/hr. Demonstrate that the overall conversion of Ain the whole process is 95% and the flowrate of A in the purge stream is 50 kmol/hr. (4 marks) b. A student claims: "There cannot be any A in the recycle stream, because 1000 kmol/hr of A enters the reactor, the conversion is 95%, so 50 kmol/hr A leaves the reactor. As the flowrate of A in the purge is 50 kmol/hr A, all the A leaving the separator flows out via the purge, so the flowrate of A in the recycle stream must be Okmol/hr" What THREE errors in reasoning has the student made? (3 marks) C. The flowrate of Bin the fresh feed is 750 kmol/hr/. The flowrate of inert impurities in the purge stream is 25 kmol/hr. Calculate the total flow rates of the fresh feed and the purge stream (4 marks) (17 marks in total)
