We have a feed mixture of 22.0 mol% methanol, 47.0 mol% ethanol, 18.0 mol% n-propanol, and 13.0 mol% n-butanol. The feed is a saturated liquid, and F = 10,000 kmol/day. Recover 99.8% of methanol in distillate, and obtain a methanol mole fraction in distillate of 0.99.

a. Find D and B.

b. Find the compositions of distillate and bottoms.

You have a sample consisting of unknown concentrations of methanol, ethanol, and 1-propanol. That is, you have one jar that contains all three of these chemicals. You don’t know the concentrations of the chemicals. You also have individual 100% solutions of methanol, ethanol, and 1-propanol. So, one jar of 100% methanol, one jar of 100% ethanol, one jar of 100% 1- propanol. You have methylene chloride to use as a solvent. determining the concentration of each alcohol in your unknown...

A process is carried out in which a mixture containing 25.0 wt% methanol, 42.5% ethanol, and the balance water is seperated into two fractions. A technician draws and analyzes samples of both product streams and reports that one stream contains 39.8% methanol and 31.5% ethanol and the other contains 19.7% methanol and 41.2% ethanol. You examine the reported figures and tell the technician that they must be wrong and that stream analyses should be carried out again. (a) Prove your...
