It is desired to distill two feeds 1 and 2 of water (W) and acetic acid (A) mixture as shown in the Figure below. Calculate the theoretical stages required for the distillation separation at 1.0 atm. Distillate 98 mol% water LID = 1.2L/Dmin Feed 1, bubble-point liquid kgmolh 75 25 1 atm 100 Feed 2, 50 mole % vaporized kgmol/h 50 50 100 Bottoms 95 mol % acetic acid Steam L WATER ( WACETIC ACID (A), 1 ATM Xw 0.0055...
1.15. Material balance for a distillation sequence. Five hundred kmol/h of liquid alcohols containing, by moles, 40% methanol (M), 35% ethanol (E), l 5% isopropanol (IP), and 10% normal propanol (NP) are distilled in two distillation columns. The distillate from the first column is 98% pure M with a 96% recovery of M. The distillate from the second is 92% pure E with a 95% recovery of E fromn the process feed. Assume no propanols in the distillate from Column...
The vapor-liquid equilibrium for n-pentane and n-hexane at 1 ATM is well approximated using a constant relative volatility of 2.95. CMO is valid. For all the problems, the feed stream is flowing at 80 mol/s and contains 45 mol% n-pentane, the feed is a saturated liquid (q = 1) at the column pressure, the distillate is 95 mol% n-pentane, and the bottoms is 10 mol% n-pentane. In this problem, you should analyze the column graphically using the McCabe-Thiele Method a....
We are separating acetone and ethanol in a distillation column with a total condenser and a partial reboiler. The column has two feeds and operates at a pressure of 1.0 atm. Feed 1 is a saturated liquid that is 60.0 mol% acetone and has a feed rate of F1 = 200.0 kmol/h. The second feed is 40.0 mol% acetone, has a feed rate of F2 = 300.0 kmol/h, and is a two-phase mixture that is 20% vapor. Assume CMO is...
