a. If feed rate in Example 11-1 is doubled, what is total bare module capital cost (column plus trays and heat exchangers) in 2020? Use Eq. (11-4) and Table 11-2 for cost data.

Example 11-1

Example 11-2

Example 11-3

Table 11-2

b. Compare the 2020 total bare module capital cost per kmol of product for the two different feed rates.

Estimate the cost in 2020 of the distillation column (shell and trays) designed in Examples 10-1 to 10-3. In addition, design and determine the cost of the reboiler and condenser (both shell and tube with floating head). Assume steam is at 140.0C in the reboiler, and cooling water enters at 30.0C and leaves at 45.0C. AC6 = 31,569 kJ/kmol and Ac7 = 34,676 kJ/kmol at their normal boiling points.
