Problem 8.3: The data below are for the system 1,4 dioxane (1)/methanol(2) at 308.5 K. a) What is the saturation pressure of methanol at 308.5 K? b) What is the phase of a mixture that contains 60% dioxane at 308.5 K, 0.1 bar? c) Determine the bubble and dew pressures of a mixture that contains 60% dioxane at 308.5 K. These questions can be answered more easily if you plot the Pxy graph based on these data.
Propane is separated from propylene by distillation. The compounds have close boiling points and the relative volatility will be low.
Prepare a PowerPoint presentation to provide an argument for or against the use of glass over PET/PEN for small-pack beer packaging.

Hardness is 160 ppm and flow rate is 40 m3/hr ,I want to know the amount resin quantity required. Please give me a solution with details.
The reflux ratio is set at 4.0:1. Calculate the kg mol/h distillate D and bottoms W and their compositions. Also, calculate the number of theoretical plates required.
The fractional distillation column will operate at approximately constant pressure of 1 atm. The reflux ratio is 2. How many theoretical plates must the column have if the feed is introduced into the eighth plate?
Design a column for this separation. The column will operate at essentially atmospheric pressure. Use a reflux ratio 1.5 times the minimum.
A closed tank, 1 m3 in volume is filled with water at 1 bar 80 °C. A second identical tank contains 20 kg of steam at 20 bar. What is the mass of water in tank 1?
One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light.
