A distillation column is a process unit in which a feed mixture is separated by multiple partial vaporization and condensations to form two or more product streams.the overhead product stream is Rich in the least volatile components.the following flowchart shows a distillation column with two feed streams and three products streams. In put given Mass flow rate 1=? Xb=0.03 , Xc=0.97 Mass flowrate 2=5300kg/h X2a=? , X2b=? Out puts given Mass flowrate 3= ?kgA/h Mass flowrate 4=1200kg/h X4a=0.7 , X4b=? , X4c=? Mass flowrate 5=? X5b=0.60 , X5c=0.40 Then find A, how many independent material balances may be written for this system. B, how many of the unknown flowrate and mole fraction must be specified before the others may be calculated? C, suppose value are given for m1&X2. Give a series of equation each involving only a single unknown,for the remaining variable.circle the variable for which you would solve.(once a variable has been calculated in one of these equation ,it may appear in subsequent equation with out being counted as an unknown)

In put given
Mass flow rate 1=? Xb=0.03 , Xc=0.97
Mass flowrate 2=5300kg/h X2a=? , X2b=?
Out puts given
Mass flowrate 3= ?kgA/h
Mass flowrate 4=1200kg/h X4a=0.7 , X4b=? , X4c=?
Mass flowrate 5=? X5b=0.60 , X5c=0.40
Then find
A, how many independent material balances may be written for this system.
B, how many of the unknown flowrate and mole fraction must be specified before the others may be calculated?
C, suppose value are given for m1&X2.
