Q4. The variables of the each stream (i) of the following chemical process are:
F$_i$, $x_{i,A}$, $x_{i,B}$, $x_{i,C}$, $x_{i,D}$, T$_i$, P$_i$ (A, B, C and D are the compounds of the
processes and D is an inert compound)
a) Consider the variable list of the streams and calculate the DOF for the
overall chemical process above.
b) Give a suitable design variable list for overall process.
c) If you use sequential modular approach and reactor is the starting unit
write the tearing stream and precedence order of calculations.
d) Make DOF analysis of mixer and write material balances by the
consideration of the variable list above.
Note: x: is mass fractions of the compounds for all of the streams.
