Question
mentals of Material Balances
fowchart shows a distillation column with two feed streams and three
The following
streams
Stream 3
m3(kg A/h)
Stream 1
m1(kg/h)
0.03 kg B/kg
0.97 kg C/kg
Stream 4
1200 kg/h
0.70 kg A/kg
4B(kg B/kg)
xckg C/kg)
Stream 2
5300 kg/h
2A(kg A/kg)
2B(kg B/kg)
Stream 5
mis(kg/h)
0.60 kg B/kg
0.40 kg C/kg
(a) How many independent material balances may be written for this system?
(b) How many of the unknown flow rates and/or mole fractions must be specified before the others
may be calculated? (See Example 4.3-4. Also, remember what you know about the component
mole fractions of a mixture -for example, the relationship between 12A and x2B.) Briefly explain
your answer.
c) Suppose values are given for imi and t2 Give a series of equations, each involving only a single
unknown, for the remaining variables. Circle the variable for which you would solve. (Once a
e has been calculated in one of these equations, it may appear in subsequent equations
without being counted as an unknown.)
