QUESTION 5
A distillation column has one inlet feed (F), and two outlets, a distillate (D) and a bottom (B) stream. The inlet feed, F = 100 kg/h, of ethanol and water, has an ethanol mass fraction of xF = 0.5. The distillate flow rate is 85 kg/h, and the bottom ethanol mass fraction is xB = 0.38. What is the total bottom flow rate, B, in kg/h?

Question 2 A feed material stream flowing at a rate of 100 kg/h is fed to a distillation column. The feed contains 45 wt.% benzene (C6H6) and the remainder toluene (C6H5CH3). The distillate stream contains 98 wt.% benzene. The bottom stream contains 10 wt.% of the benzene fed to the distillation column. a) Draw a block flow diagram of the process and annotate appropriately with the data provided, state the basis and define variables for unknown flow rates and compositions....

A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...

4.6. A distillation column is a process unit in which a feed mixture is separated by multiple partial vapor- izations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture (the ones that vaporize most readily), and Equipment Encyclopedia distillation column the bottom product stream is rich in the least volatile components. The following flowchart shows a distillation column with two feed streams and three product...

I mostly need help setting up what two equations I need to use A liquid feed stream (F, 200 kg/h) mixture containing 25% benzene and 75% toluene by weight enters a distillation column. The column produces two product streams (D and B). The product leaving the top of the column (D) is 98% benzene by weight, and contains 95% of all the benzene leaving the system. Write a system of two linear algebraic equations to solve for the mass flow...

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...
