Calculate the cost of column plus trays, reboiler, and condenser for Example 11-1 using Luyben's cost data. The answers are in the example. In addition, calculate TAC for the entire system if Luyben's equipment cost data are used. Payback period is 3 years, cooling water is \(\$ 0.50 / \mathrm{GJ}\), low-pressure steam is Luyben's value in Table 11-9, and operation is \(8000 \mathrm{~h} / \mathrm{yr}\). Assume that Luyben's cost data are from 2012 and update to 2020.

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.
