100mole of liquid mixture containing 50% n-heptane and 50% n-octane at 30oC is continuously flash vaporized at 1atm. Find the quantity and composition of of liquid and vapor streams. Flashing temperature is 113oC.
1- Assume (L/V)1 =1.
2- Calculate Sx1=0.992 and Sy1=1.008 .
3- Sx ≠1 and Sy≠1assume another L/V
4- Assume (L/V)2 =0.5
5- Calculate Sx2= 1.005 and Sy2= 0.9975 .
6- Interpolate for any of them say Sx.
The vapor and liquid compositions:
