NOx Control

NOx is a term representing a family of 7 nitrogen oxide compounds: nitric oxide (NO) and nitrogen oxide (NO2) are the two most prevalent compounds present from combustion processes. NO and NO2 are considered atmospheric pollutants as they contribute to smog and acid-rain. Many State and Federal environmental authorities throughout the world impose strict regulations on the maximum concentration (ppm) and mass (kg per day/year) of these NO and NO2 contaminants that end user sites can discharge into the air. In many cases, fines are given for exceeding concentration limits and taxes on mass discharge. ApHinity has developed a process for nitric oxide and nitrogen oxide destruction. The ApHinity process is a 2-stage process of NOx abatement that utilizes existing on-site equipment, thus greatly limiting CAPEX investment requirements. The ApHinity process for NOx destruction is protected under multiple US and international patents, starting with the conversion of nitric oxide to nitrogen dioxide using gas phase chlorine dioxide. Nitrogen Dioxide is absorbed into scrubber solution via the patent pending non-sulfur based organic additive in the second step of the reaction process. This combination 2 step NOx destruction process with gaseous chlorine dioxide and organic additive is efficient and cost effective compared to competitive 3 stage scrubbing technologies. Removal efficiency rates over 99% are capable using the combination of proprietary processes.
