A chemical separation system is used to separate benzene, styrene, toluene, and xylene with an 70% benzene 65% styrene D array of distillation columns shown in Figure 1. Experimental data show that the feed rate (stream 25% toluene 5% xylene 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 %). II 30% benzene 35% styrene The following information is available for this system: I 75% toluene E 95% xylene i. 70% benzene, 65% styrene, 25% toluene and 5% xylene of stream B go overhead to 15% benzene 20% styrene stream D. The remainder goes out the bottom to stream E. F 30% toluene 85% benzene 35% xylene 65% styrene ii. 85% benzene, 60% styrene, 20% toluene and 10% xylene of stream C go overhead to 20 % toluene C stream F. The remainder goes out the bottom to stream G. III 10% xylene 15% benzene 35% styrene 80% toluene 90% xylene Figure 1. Distillation column train 2.1.
