What is NOx? And why are NOx emissions important in air quality? Can you write (at least one
of) the involved chemical reactions? Assuming a Brayton cycle, discuss three mechanisms or
trends that can affect the NOx production. How is building pollution categorized? Discuss the
importance of a building's operational schedule on its emissions production.
Solution
As the nitrogen released during fuel combustion, it combines with oxygen to form nitric oxide
(NO) and further combines with oxygen to form nitrogen dioxide (NO2). Nitric oxide is not
considered to be hazardous to health at typical ambient condition whereas as nitrogen dioxide
can be hazardous. NOx (Oxides of nitrogen) is referred to together for nitrogen dioxide and nitric
oxide.
NOx are the important polltants in air. It is strong oxidizing agents and takes a major role in
atmospheric reactions.
