CataStak is a portable, low-temperature Selective Catalytic Reduction (SCR) system. It is capable of reducing NOx emissions
by as much as 90%. CataStak consists of a single-reactor housing with catalyst and an ammonia injection skid. The skid holds
three ammonia cylinders, an ammonia header, and associated instrumentation and controls. CataStak is available with most
Nationwide Boiler rental units. It is also available as an add-on for existing and new package boilers.
As allowable stack emission regulations become more stringent, boiler owners seek the lowest possible emissions to meet the
newest standards, to add plant capacity without increasing overall plant emissions, or to minimize NOx emission offset costs.
These costs have been over $80,000 per ton. CataStak can substantially reduce NOx, as well as VOC and CO emissions.
CataStak is designed as a cost effective answer to reducing stack emissions. It does not require ammonia storage tanks,
ammonia vaporizers, and complicated control systems based on NOx measurements. Rather, it is designed for stand-alone
operation with minimum operator intervention.
Advantages
- Easy field retrofit - no burner or fan changes required
- Simple controls - minimum operator intervention
- Low operating cost
- Stand-alone operation
- Dramatic reduction in stack emissions
