The UtA System basically reverses the process used to make urea. A urea solution is fed into a reactor, where it is heated under pressure to produce a gas mixture of ammonia, carbon dioxide, and water vapor. This gas mixture is then delivered to the point of use.
DeNOx/SCR systems are used in the following plants:

Removal of Oxides of Nitrogen – N0x can be achieved by injecting Ammonia into the air and passing the resulting mixture over a catalyst.
Selective Catalytic Reduction – SCR involves the use of a catalyst that is selective to promote the reaction of Ammonia and N0x to form Nitrogen and water. Read more...More Product Announcements from Branch Environmental Corp.
While scrubbing is obviously possible, using special chemicals or other techniques, it is a much more costly approach than a conventional scrubber. Both initial cost and operating costs are higher.
Conditions involving high temperatures or low concentrations – which limit scrubbing effectiveness – are better suited to SCR technology. Read more...More Product Announcements from Branch Environmental Corp.
