A column with similar dimensions, number of trays, and operating at the same conditions as given in

Question:

A column with similar dimensions, number of trays, and operating at the same conditions as given in Problem 7.19 is to be used to separate a mixture containing the following chemicals. For each case determine the bare module cost using CEPCI = 542.

10% nitric acid solution

50% sodium hydroxide solution

10% sulfuric acid solution

98% sulfuric acid solution


Problem 7.19

A distillation column is initially designed to separate a mixture of toluene and xylene at around 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 CEPCI = 542.
