CHEMICAL Engineering

Compare the total installed cost (TIC) estimates (in 2016 dollars) for a thermal oxidizer designed to treat 40,000 scfm of contaminated air at 1700°F if it is equipped with either (a) 40% recuperative or (b) 95% regenerative heat recovery. Use the information provided below for this problem.

Explanation / Answer

Solution:

The given graph has the values in US dollar in 1992 for regenerative oxidizer.

So we will see the value for regenerative oxidizer for 40000 SCFM capacity, From graph the cost is,

Around 1250 * 1000 US$

TIC = 1250000 US$

As we all know the US$ experienced inflation at an average rate of 2.24% per year. So 100$ in 1992 means 170$ in 2016.(refer literatures for this figure)

So our TIC in 2016 dollars is,

TIC = 1250000 * 1.7

TIC = 2.125 Million US Dollars
