Sec. 4.2 Scale-up of Liquid-Phase Batch Reactor Data to the Design of a CSTR 143

The specified production rate in lb mo!/min is
Ib
1 yr
1 h
Fc=2xlo*-x-x-- 1 day x---,x-- llbmol - 6.137 Ib -- mol
yr 365 days 24h 60mm 621b min
From the reaction stoichiometry
FC = FAOX
we find the required molar flow rate of ethylene oxide to be

We can now calculate the reactor volume using the following equations:

Figure E4-2.1 Single CSTR.

1. Design equation:

v= - (E4-2.1)
-rA
2. Rate law:

-TA = kCA (E4-2.2)

3. Stoichiometry. Liquid phase (u = v,) :
cA= cAo(1-x) (E4-2.3)
,I. Combining:

(E4,-2.4)
