A distillation column is initially designed to separate a mixture of toluene and xylene at around
18. ambient temperature (say, 100°C) and pressure (say, 1 barg). The column has 20 stainless steel valve
trays and is 2 m in diameter and 14 m tall. Determine the purchased cost and the bare module cost
using a CEPCI = 500.

A column with similar dimensions, number of trays, and operating at the same conditions as given in
Problem 18 is to be used to separate a mixture containing the following chemicals. For each case
determine the bare module cost using a CEPCI = 500.
a. 10% nitric acid solution
19. b. 50% sodium hydroxide solution

c. 10% sulfuric acid solution
d. 98% sulfuric acid solution

Hint: you may need to look for the relevant MOC for part (d) on the Internet or another resource.

It is recommended that the following problems be solved using CAPCOST (use a value of CEPCI =
500).

Determine the bare module, total module, and grassroots cost of the following.
