A two-stage separation unit is shown in Figure 3.1. One thousand kg/ hr [1000 kg/hr] of a mixture of Toluene (1) / Benzene (2)/Xylene (3) [compositions in mass fraction] enter the process through the input stream [Stream 1] Determine: 2.5 2.6 2.7 How many equations are needed to solve for all unknows? Do all the equations needed to solve for the unknowns in the process have to be "material balance" equations? Yes? No? Why? Is there a "Tie "component in this process? If so, which one? Why? 0.99 Benzene Tolune m = 1000 kg/hr Unit 1 Unit 2 1 0.4 Benzene 0.4 Toluene Xylene 3 Toluene 0.05 Xylene 5 0.1 Toluene Xylene
