A chemical separation system is used to separate benzene, styrene, toluene, and xylene with an array of distillation columns shown in Figure 1. Experimental data show that the feed rate (stream A) is 100 mole/hr and that the composition of stream A is 15% benzene, 20% styrene, 30% toluene and 35% xylene (compositions are in mole %). The following information is available for this system: i. 70% benzene, 65% styrene, 25% toluene and 5% xylene of stream B go overhead to stream D. The remainder goes out the bottom to stream E. ii. 85% benzene, 60% styrene, 20% toluene and 10% xylene of stream C go overhead to stream F. The remainder goes out the bottom to stream G. Use OCTAVE or MATLAB coding. 70% benzene 65% styrene D 25% toluene 5% xylene II 30% benzene A 35% styrene I 75% toluene E 15% benzene 95% xylene 20% styrene F 30% toluene 85% benzene 35% xylene 65% styrene 20 % toluene C III 10% xylene 15% benzene 35% styrene G 80% toluene 90% xylene Figure 1.
