Happy Elroy-maticTM announcement: You must base your solutions for these problems equation vapor pressure correlations in the form of Antoine's on Pat Ba =Ai-T+Ci Hg 1 mm with the following parameter values: compound i A B (K) 15.9008 2788.51 -52.36 16.0137 3096.52-53.67 16.0195 3279.47-59.95 Ci (K) benzene toluene ethylbenzene 11-propylbeuzene | 16.0062 3433.84 -66.01 -butylbenzene 16.0793 3633.40-71.77 Note tlhat T is in K and Pt is in mm Hg. More data are need (just as, in real life, more data are available in the library and on the internet than you need). given than you 4. (Lecture L04) A 15 mol/minute feed stream comprising 57 mole percent toluene and 43 mole percent ethylbenzene undergoes flash distillation at atmospheric pressure with 35 percent vaporization (f 0.35). a. Use the graphical procedure to determine the compositions of the vapor (distillate, top) and the liquid (bottom) products, and also the temperature of the flash. b. Perform the analysis using the algebraic (non-graphical) method.

The xy data cab be obtained from the following equation:

x= (P_total - P^o _ethylbenzene )/ ( P⁰ _toluene - P^o_{ethyl benzene} )

y= (P_toluene * x)/ P_total
