I just need Part E
Propene reacts with hydrogen bromide to produce 1-bromopropane in a PFR. A 70:30 mixture of propene and hydrogen bromide is fed at a rate of 750 m3/hr at 120C and 3 atm. The reaction rate is second order; first order with respect to each of the reactants.
The reaction is as follows: CH3CH=CH2 + HBr n-C3H7Br
Specific reaction rate constant: k [m3 * kmol-1 * s-1] = 1.56 x 1010 exp(-89 (kJ/mol) / RT) (Use the IDEAL property method)
a. The required PFR reactor volume to achieve a 23% conversion of the limiting reactant if the PFR reactor diameter is 7 ft and is operated isothermal. (RESULT: V=1.76m3)
b. Determine the conversion of the limiting reactant, if the reaction were performed in the PFR from part (a) operated adiabatically. In addition, discuss the differences in conversion obtained between the isothermal PFR and the adiabatic PFR reactor. (RESULT: X=1)
c. Determine the time required to achieve a 23% conversion of the limiting reactant in an isothermal batch reactor. (RESULT: t=2.86923min)
d. Determine the residence time required to achieve a 23% conversion of the limiting reactant in an isothermal CSTR reactor. (RESULT: t=0.0563478hr)
e. Calculate by hand the volume and residence time of the isothermal PFR from part (a), the batch operation time from part (c), and the CSTR volume and residence time from part (d). Include analytical calculations and solutions in the report appendix.
