I posed this question on the other forum also. How is something eradicated as stated? Would this not actually neutralize or change the chemical make-up to something else?
 I was a power plant operator for 34 yrs. The plant I worked at had catalytic reduction systems for NOx control. It used ammonia sprayed over the catalyst bed to reduce the emissions , it did not eradicate anything, it actually added ammonia the the mix. http://www.pollutiononline.com/doc/breakthrough-co-technology-eliminates-vehicle-exhaust-fumes-at-the-source-0001
