A→P−rA=kACA[ mol m−3 s−1] The reaction is carried out in a non-ideal reactor, containing two immiscible liquid phases. The compounds A, P are located (exclusively) in the dispersed phase. The continuous phase is ideally mixed. For the dispersed phase, the RTD diagram has been determined experimentally and is given in Figure P1: Figure P1:E(t) curve of the dispersed phase The average residence time in the reactor equals 100 s. a) Calculate the values of a and t⋆. a=0.0088 s−1 and t∗=28.6 s If you were not able to determine the value of a and t⋆ in question a) then assume that a=1.25⋅10−2[ s−1] and t∗=20[ s]. b) Give a plot (according to scale) of the F(t)-curve. It is known that ideal micro-mixing prevails within the reactor, and an experimental value of kA=0.0167 s−1 was obtained from laboratory experiments at the same conditions as the reactor is operated. c) Determine the conversion in the reactor. d) Also, determine the conversion of A if: X=0.80 i. the tanks-in-series model applies, and X=0.80 ii. the reactor is modelled as an ideal PFR. X=0.81 (7) Discuss differences / agreement with the answer obtained at c).
