D23. We wish ro flashdistill 1000 kmol/h of a feed that is 40 molyo methane, 5 mol% ethyl_ene, 35y" mole ethane, and 20 molo/o n_hexane. Drum pressure is 2500 kpa and drumtemperature is 0.C. Use the Depriester charts. Find V/Il x1, y;, ! ED24, We plan to separate a mixture or propane and n_hexane at 300 kp.r.a. Using the data in the Depriester charts, plot y propane versus x propane 1br thisrruxture at this pressure.b. ff th€- feed is 30 molo/o propane, and 40 mol% of the feed is vaporized, what are theliquid and vapor rnole fractions, and what is the drum temperature? Solve graphi_calyc. What is the drum temperature in palt b?d. If y = 0.8and the feed is 0-6(both mole fraction propane), what is the valueof V/F?_ - _ e. Use the Rachford-Rice equation to check the answers obiained in parts b and c.D25. We wish to flashdistill a mixture of methane and n_butane in a flashdrum operating at50'C. The feed is 20 molyo methane and g0 mol% n_butane.
