NOx reduction
NOx reduction
(OP)
I am wondering if anyone has any experience or knowledge on the low temperature oxidation of NO to N2O5. The technology is trademarked as LoTOx.
I have looked at SNCR and SCR in the past and found a lot of material in journals and online. However, with LoTOx I seem to be hitting a dead end.
I am looking for information relating to disadvantages or limitations with the system. Is ozone too expensive? Is it limited by the NOx levels entering the unit?
The best information I have is done by BOC.
Cheers

RE: NOx reduction
The site currently uses thermal and modified SCR, both very expensive to operate.
I called the person responsible for the evaluation and was told that he has take a position in technical sales, smart move. The person filling in didn't know anything as he hasn't done his own evaluation, they didn't seem too enthusiastic about the new project.

RE: NOx reduction
HNO2 + H2O2 -> HNO3 + H2O
The hydrogen peroxide can be added directly to nitric acid pickling solutions to prevent the escape of the nasty reddish NOx fumes, plus it regenerates some nitric.
Or, it can be used on cooled flue gases, as nitric is more easily scrubbed than NOx.
The limitation is that hydrogen peroxide has a relatively short life (self-decomposes) above about 50oC.

I am curious as to why I have not seen more information on LTO. In our application now we have fairly low NOx already and we do not need a wet scrubber, so I would suspect that a system such as SNCR would work best for us. But I am having trouble convincing people without any information on LTO.
