P 6 . 1 1 - ELEMENTS OF CHEMICAL REACTION NGINEERING FIFTH EDITION ( H . SCOTT FOGLER ) Pure butanol is to be fed

P6.11- ELEMENTS OF CHEMICAL REACTION NGINEERING FIFTH EDITION(H. SCOTT FOGLER)
Pure butanol is to be fed into a semibatch reactor containing pure ethyl acetate to produce butyl
acetate and ethanol. The reaction
CH3COOC2H5+C4H9OHCH3COOC4H9+C2H5OH
is elementary and reversible. The reaction is carried out isothermally at 300K. At this temperature,
the equilibrium constant is 1.08 and the specific reaction rate is 910-5dm3mol*s. Initially, there
is 200dm3 of ethyl acetate in the vat, and butanol is fed at a volumetric rate of 0.05dm3s. The
feed and initial concentrations of butanol and ethyl acetate are 10.93moldm3 and 7.72moldm3,
respectively.
(a) Plot and analyze the equilibrium conversion of ethyl acetate as a function of time.
(b) Plot and analyze the conversion of ethyl acetate, the rate of reaction, and the concentration of
butanol as a function of time.
(c) Rework part (b), assuming that ethanol evaporates (reactive distillation) as soon as it forms.
(d) Use ODE solver to learn the sensitivity of conversion to various combinations
of parameters (e.g., vary FB0,NA0,v0).
