Optimize the design of a distillation column to separate 225 metric tons per hour of an equimolar mixture of benzene, toluene, ethylbenzene, paraxylene, and orthoxylene with minimum total annualized cost. The feed is a saturated liquid at 330 kPa. The recovery of toluene in the distillate should be greater than 99%, and the recovery of ethylbenzene in the bottoms should be greater than 99%.
A mixture containing 98 mol% methanol and 2 mol% of an inert contaminant is available as a feed to a formaldehyde plant. The fresh feed to a process consists of 1000 kmol/h of this mixture along with 200 kmol/h of oxygen. All of the oxygen is consume..
Determine the composition of the vapor at boiling point and determine the Dew point of the mixture - determine the composition of streams leaving the first FV unit.
The vessel is 4 m internal diameter and 20 m long. Estimate the minimum wall thickness required to resist this pressure, for the cylindrical section and the heads. Take the design pressure as 12 bar and the maximum allowable stress for the materia..
Gas oil at 200 °C is to be cooled to 40 °C. The oil flow rate is 22,500 kg/h. Cooling water is available at 30 °C and the temperature rise is to be limited to 20 °C. The pressure drop allowance for each stream is 100 kN/m2 . Design a suitable exch..
Adipic acid is used in the manufacture of nylon 6,6. It is made by hydrogenation of phenol to a mixture of cyclohexane and cyclohexane (known as KA oil-ketone and alcohol), followed by oxidation with nitric acid.

Calculate the atomic weight (in amu) of an element (X), given the following data: 24X : 24.000 amu at 0.7879 fractional abundance 26X : 26.000 amu at 0.1017 fractional abundance 25X : 25.000 amu at 0.1113 fractional abundance
A storage tank for concentrated nitric acid will be constructed from aluminum to resist corrosion. The tank is to have an inside diameter of 6 m and a height of 17 m. The maximum liquid level in the tank will be at 16 m.
A distillation column separates benzene from toluene using a control scheme similar to that shown in Figure (a). Make a practice HAZOP study of the plant section and add any instrumentation that is needed to develop the full P and I diagram.
