A process for making a single product involves reacting two liquids in a continuously agitated reactor and distilling the resulting mixture. Unused reactants are recovered as overhead and are recycled. The product is obtained in sufficiently pure form as bottoms from the distillation tower.
(a) Prepare a qualitative flow sheet for the process, showing all pieces of equipment.
(b) With cross reference to the qualitative flow sheet, list each piece of equipment and tabulate for each the information needed concerning chemicals and the process in order to design the equipment.

The lower flammable limit (LFL) of methanol in air is 6.0 mole%. Calculate the temperature at which the equilibrium percentage of methanol vapor in a saturated methanol-air mixture would equal the LFL. (This temperature is a rough estimate of the ..
Calculate the final solution volume and the shaft work in kW that the pump must deliver, assuming that the surface of the stored solution and the pipe outlet are both at 1 atm. Data. PH2O = 1.00 kg/
In Figure 9.84, calculate the force that exists between the two faces of the gap. The magnetic path has a permeability equal to μ and the core is d m thick. a, b, and g are the average path lengths of the corresponding magnetic path sections.
Calculate the maximum temperature in the fuel rod, if the outersurface of the cladding is in contact with a liquid coolant at temperature TL, the heat transfercoefficient of the cladding-coolant interface being hL. The thermal conductivities of fu..

Write reactions to show how these strong electrolytes break apart when they dissolve in water.
We can use z-transforms to find the sum of integers raised to various powers. This is accomplished by first recognizing that the sum is the solution of the difference equation
A shell and tube heat exchanger is to be used in a corrosive service. If carbon steel tubes are used, the cost of the exchanger is estimated to be $160,000, and it is expected that the exchanger will need to be replaced after two years.
The estimated cost of the pipes, per unit length is: schedule 40 carbon steel $5, schedule 80 carbon steel $8.30, stainless steel (304) schedule 40 $24.80. Installation and fittings for all the materials adds $16.5 per unit length. The downtime re..
