Question

1 Approved Answer

The following liquid - phase reactions happen simultaneously: A B , r 1 = k 1 C A B C , r 2 = k

The following liquid-phase reactions happen simultaneously:
AB,r1=k1CA
BC,r2=k2
AD,r3=k3CA
The reactions are carried out isothermally with a feed of pure A having an initial concentration C40=3molL, and a feed rate of 20Ls(assume no density change on reaction). The fractional conversion of A(xA) at the exit of the reactor is 0.80. The current reactor used is a Continuously Stirred Tank Reactor (CSTR) because of
simplicity.
a) What should be the volume of CSTR used?
b) Find CAA,CBB and yield of B(YB).
c) Derive the expression for maximum CB at an optimum residence time? What is the maximum yield of B(i.e. yield at maximum conversion of B)?
Other data:
B is the desired product. C and D are undesired side products.
k1=10-2s-1
k2=10-3molL-s
k3=10-2s^(-1)
CB0=0
C_(C_0)=0
CD0=0
