Patent Issued to R.F. 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

History and Founder
An objective for all of us in life is to potentially leave a part of ourselves as we depart this life for another. There are many adjectives that can be used to describe our founder Bob MacDonald but perhaps none more appropriate than ‘persistent.’
From Bob’s personal desk to the growth of our ten-office company, and ultimately his fight with cancer, persistence was his unwavering theme. In the memory of our founder, may these words by Calvin Coolidge be an inspiration to you.
Persistence – A Quote by Calvin Coolidge
Nothing in the world
can take the place of persistence.
Talent will not;
nothing is more common than
unsuccessful men with talent.
Genius will not;
unrewarded genius is almost a proverb.
Education will not;
The world is full of educated derelicts.
Persistence and determination
alone are omnipotent.
The slogan ‘Press On’ has solved
and always will solve
the problems of
the human race.

Furthermore, he followed up with me at 8 p.m. that same night to see how things went!
