Control Of Nox In Alkaline Media With Tertiary Butyl Hydroperoxide, David R. Edwards

Theses

Alkaline solutions of tert-butyl hydroperoxide (TBHP) selectively remove NO from simulated flue gasses. The investigation was conducted in a bubbling scrubber. NO removal efficiency of the scrubbing solutions was evaluated as a function of various operating parameters such as pH, oxidant concentration, oxidant to base mole ratio, residence time, temperature and flue gas compositions.

Alkaline solutions of TBHP show promise of being an economical choice for the selective removal of NO from flue gas. Solutions containing 0.2 M TBHP, 0.03 M NaOH (pH 12.5), and 1 minute NO residence time remove NO to below detectable levels at 53°C. The source, …
