P12-7B Use the data in Problem P11-4A for the following reaction.
Th elementary, irreversible, organic liquid-phase reaction
A+BlongrightarrowC
is carried out in a flow reactor. An equal molar feed in A and B enters at 27C, and the volumetric
flow rate is 2dm3s and CAO=0.1kmolm3.
Additional information:
HA(273K)=-20kcalmol,HB(273K)=-15kcalmol,
HC(273K)=-41kcalmol
CPA=CPB=15calmol*K,CPC=30calmol*K
k=0.01dm3(mol)*sat300K,E=10,000calmol
Ua=20calm3??sK,mC=50gs
Ta0=450K,CPcatm=1calg?KThe reversible reaction (part (d) of P11-4A) is now carried out in a PFR with a heat exchanger. Plot
and then analyze x,xe,T,Ta,Qr,Qg, and the rate, -rA, for the following cases:
(b) Constant heat-exchanger temperature Ta
(c) Co-current heat exchanger Ta(Ans.: At V=10m3 then x=0.36 and T=442K)
(d) Countercurrent heat exchanger Ta(Ans.: At V=10m3 then x=0.364 and T=450K)
(e) Adiabatic operation
(f) Make a table comparing all your results (e.g.,x,xe,T,Ta). Write a paragraph describing what
you find.
