Problem 1.
Consider the
following multiple reactions:
A
+ B ------ 2·C k1,A:
10 L/mol·s
A
+ C ----- D + E k2,D:
10-2 L/mol·s
B
+ C -------E + 2·F k3,C:
100 L/mol·s
B
+ E ------- C k4,E:
1 L/mol·s
The reactions,
in liquid phase, are to be carried out in a PFR reactor of 10 dm3 at
a temperature of 300K and a pressure of 1 atm. The entering volumetric flow is
1800 mL/min. The molar feed flow rate is 108 mol/h. The feed molar ratio A/B is
4/1.
Determine:
a. Feed massic flow of A (PMA: 60
g/mol)
b. The concentration of B in the feed
(mol/L)
c. The net reaction rates of each species
d. The molar or mass balances for the
reactor design
e. Write the POLYMATH program to determine
all concentrations and XA. Do not forget initial conditions.
