A distillation column is separating a feed that is 40 mol%
methanol and 60% water. The two phase feed is 60% liquid.
Distillate product should be 92% methanol and bottoms 4 mol%. A
total reboiler and a total condenser are used and reflux is
saturated. Operation is at atmospheric pressure with a reflux ratio
of 0.9. Under these conditions, HG = 1.3 ft and HL = 0.8ft in both
the stripping and enriching sections. Determine the required
packing height in...

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....
separation processes
The goal is to separate methanol from water using distillation. We have a 50-50 feed input as a two-phase mixture with 50% vaporized coming in at 500 kmol/hr. The column is well insulated and has a total condenser. A reflux is set to 2 and returned as saturated liquid. The composition in the distillate and bottoms are to be 0.95 and 0.05 mole fractions, respectively. The column is at 1 atm. If 100 kmol/hr were taken off as saturated liquid...

The distillation column shown at the right is used to separate compound A from compound B in an adiabatic fashion. A liquid mixture of A and B is fed at a specified temperature into a distillation column (stream 1). At the top of the column, a vapor stream that is A-rich (stream 2) passes through a condenser that completely condenses the mixture. Half of this liquid leaves the condenser as the overhead product (stream 4), and half of the liquid...

1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...

Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
