Learning Goal: I’m working on a environmental engineering question and need an explanation and answer to help me learn.Hello,I have an assignment and it has been already corrected by the teacher but I got a low grade. the teacher is already have made some comments to the wrong answers which it can be helpful to solve them and get the full complete correct answer. I have attached the assignment, book, and the corrected assignment with comments. Moreover, the book: chapter 13,15, and 16.

Learning Goal: I’m working on a environmental engineering multi-part question and need an explanation and answer to help me learn.Many authors report that in VOC incinerators the steps leading to the formation of CO and
H2O are relatively fast and that the oxidation of CO to CO2 is slower, so the size of the
incinerator is determined by the size required to complete the CO oxidation. Test this idea
with the following calculations:
a. Estimate the time required to combust 99 percent of the toluene in a waste stream
containing 5000 ppm of toluene at 1400oF; use the values in Table 10.4. (10 points)
b. Assume that the following step is instantaneous:
7 8 2 2 C H O CO H O + → + 5.5 7 4
and, then
estimate the time required for the step:
2 2 CO O CO + → 0.5
. Assume the kinetics are given

124,500 BTU/gal, and density 7 lb/gal). Combustion occurs with 50% excess air. Assume
65% of fuel nitrogen converts to NO, and that fuel NO is 40% of total NO (the remainder being
thermal NO). Calculate a) the NO concentration (ppm) in the exhaust gas (dry basis, ignore
water formed) and b) the production of NO (lb/hr). (25 points)
