Balances on Chemical Processes 9 2 3 4 Example 10.3-1 A stream containing 35wt% benzene (B), 50% toluene (T), and the balance xylene (X) is fed to a distillation column. The overhead product from the column contains 67.3 wt% benzene and 30.6 % toluene. The bottoms product is fed to a second column. The overhead product from the second column contains 5.9 wt% benzene and 92.6% toluene Of the toluene fed to the process, 10% is recovered in the bottom product from the second column, and 85% of the xylene fed to the process is recovered in the top product from the second column. Assume Isothermal process operations. 5 6 7 8 a) Set up the equations for all unknown stream variables, 9 b) Perform a df analysis on this process, 10 c) Outline a manual calculation procedure to determine the compositions of all streams d) Determine the values of all stream compositions 11 [[ 12 COLUMN 1 COLUMN 2 13 Solution: 122 X280.673 X27-0.306 XXX 11) Xin 035 X17-05 Xxx 42 113 XAR NI..
