Question

chemical engineering

Estimate the TIC (in 2016 dollars) of a catalytic incinerator with 35% heat recovery. The 20,000 scfm solvent-in-air stream is at 600°F when it flows into the device. Use the information provided below for this problem.

                                                                        P = exp(a + bQ)                                                     (1)

where P = manufacturer’s f.o.b. price, in 1988 dollars

           Q = waste gas flow rate, thousands of scfm

           a, b = curve fit constants (see Table below)

Explanation / Answer

At 35% efficiency, a= 11.6 and b = 0.0342

Q = 20

Thus, the value of P is as follows:

P = exp(a+bQ)

= exp ( 11.6 + 0.0342x20)

= 216209 dollars
