Aliquid mixture containing 45.0% benzene (b, mbenzene = 78.11 g/mol) and 55.0% toluene (t, mtoluene = 92.14 g/mol) by mass is fed to a distillation column. a product stream leaving the top of the column (the overhead product) contains 95.0 mole% b, and a bottom product stream contains 8.00% of the benzene fed to the column (meaning that 92.0% of the benzene leaves with the overhead product). the operation is continuous and at steady state. the volumetric flow rate of the feed stream is 1.00 × 103 l/h and the specific gravity of the feed mixture is 0.872. 1. determine the mass flow rate and composition (mass fractions) of the overhead and bottom product streams by solving the equations manually. you have to (a) choose the basis of calculation; (b) draw and label a flowchart; (c) convert all quantities to one basis; (d) perform the degree-offreedom analysis; (e) state which terms in the general balance equation (accumulation = input + generation – output – consumption) can be discarded and why; (f) write balances (benzene, toluene, and overall); and (g) determine unknowns (show equations with values, units, and conversion factors).
