MacDonald Co. for NOx Emissions Reduction Technology With the help of Michael MacDonald and the Boiler Special Projects Group, R.F. MacDonald Co. has invented and now patented the safest NOx emissions reduction process for boilers and fired vessels using direct urea injection with SCR. On Tuesday, Nov. 24, 2020, the U.S. Patent and Trademark Office issued the safest and simplest NOx-reduction process patent for packaged boilers. The patent was granted to R.F. MacDonald Co. for inventing a “process for direct urea injection with selective catalytic reduction (SCR) for NOx reduction in hot gas streams and related systems and assemblies.” SCR requires the use and storage of ammonia-based reagents, which range from high risk to low risk. The R.F. MacDonald Co. patent specifies urea, which is the lowest risk ammonia-based reagent. The only health hazard associated with urea is “possible irritation” as indicated by the Hazardous Materials Identification System (HMIS). The urea solution is identical to Diesel Exhaust Fluid (DEF), which is sold worldwide in automotive retail stores for use in diesel motor vehicles. As shown in the graphic below, urea is injected at each Injection Point into the boiler. As NOx and urea pass through the NOx Reduction Catalyst, NOx is separated into two non-harmful elements Nitrogen (N2) and water (H2O). Read More LEARN MORE ABOUT THE R.F. MACDONALD CO.
