Absolute or 100% ethanol is produced from a mixture of 95% ethanol and 5% water using the Keyes distillation process. A third component, benzene, is added to lower the volatility of the alcohol. Under these conditions, the overhead product is a constat-boiling mixture of 18.5% ethanol, 7.4% water and 74.1% benzene. Use the following data to calculate the volume of benzene that should be fed to the still in order to produce 250 litres of absolute ethanol: density of 100%...

The ethanol-water mixture is separated on a distillation column. Feed contains 20% ethanol and 1000 kmol / hour speed is entering the system. The feed temperature is 30ºC and its enthalpy is 15kcal / kg. Saturated feed steam enthalpy 485 kcal / kg and saturated feed liquid enthalpy 70kcal / kg. Distillate has at least 80% ethanol and 2% ethanol concentration of the sub-product is required to be. The feedback / distillate ratio is 5/3. System pressure is 1 atm....

After fermentation, a mixture of ethanol and water is sent to a small distillation column. At the top of the distillation column, a 95% ethanol solution at 65°C is produced at a flow rate of 3.5 kg/s. Your job is to design a double-pipe heat exchanger that will cool the 95% ethanol mixture to 40°C by using cooling water that is available at 10°C. Assume an outlet temperature of the cooling water of 55°C, and only use Schedule 40 pipe...

1. A mixture of ethanol (ethyl alcohol, C2H6O) and water contains 70.0% water by mass. Assuming volume additivity of the components, estimate the specific gravity of the mixture at 20 oC. What volume (in liters) of this mixture is required to provide 100 mol of ethanol? Molecular weight and density of ethanol are 46.07 and 789g/L, respectively. 2. A gas stream contains 18.0 mole% hexane and the remainder nitrogen. The stream flows to a condenser, where its temperature is reduced...

If a mixture of water-ethanol containing a significant amount of methanol is being distilled (separation by VLE), can we state that the methanol is not a problem because it boils off first?

A liquid mixture containing ethanol (55.0wt%) and the balance water enters a separation process unit at a rate of 90.5 kg/s. A technician draws samples of the two product streams leaving the separator and analyzes them with a gas chromatograph, obtaining values of 86.2wt% ethanol (product stream 1) and 10.9% ethanol (product stream 2). The technician then reads a manometer attached to an orifice meter mounted in the pipe carrying product stream 1, converts the reading to a volumetric flow...
