For a 500 MWe plant reducing NOX from 0.50 lb/MMBtu to 0.05 lb/MMBtu and 85 percent capacity factor (this is conservatively high for most coal boilers), approximately 3,400 tons/yr of ammonia (anhydrous equivalent) or about 6,100 tons/yr of urea (as 100 percent urea) would be needed.
It has been reported before that an increased excretion of orotate in sick children may not be uncommon and that a positive allopurinol load test may indicate unrecognized mitochondrial disease, making orotic acid as a potential marker of mitochondrial dysfunction [ 35 ] . A potential link between mitochondrial cytopathies and urea cycle dysfunction has also been suggested by the findings of hypocitrullinemia in patients with neurogenic weakness, ataxia and retinitis pigmentosa (NARP) syndrome (Mendelian Inheritance in Man database *551500) caused by a T8993G mutation in mtDNA that triggers ATPase deficiency [ 36 37 ] . It was hypothesized that the NARP mutation would cause complex V deficiency in the small intestine as well, thus reducing the availability of mitochondrial ATP required for citrulline synthesis.
Ammonia and urea are the reagents used along with a catalyst to remove NOX from the flue gas stream.
24 For example, reducing one pound of NOX will require roughly 0.176 kg of ammonia or about 0.312 kg of urea.
The major components of an SCR system include: ■ Ammonia or urea storage ■ Ammonia vaporization system (if aqueous ammonia is used) ■ Urea to ammonia converter (if urea is used) ■ Ammonia or urea metering and controls ■ Dilution air blowers ■ Ammonia injection grid ■ Catalyst ■ Catalyst reactor, ductwork and support steel ■ Catalyst cleaning devices (soot blowers, sonic horns, etc) ■ Instrumentation
