The process that is used to lessen NOx emissions and control air pollution is called Selective Catalytic Reduction. The harmful emissions are converted into nitrogen and water. This process involves catalytic reactions of either ammonia steam or air injected into exhaust pipes holding the NOx gases. The gases then mix thoroughly reducing the NOx once they pass through the catalytic bed. The catalyst main function is to promote the reduction of the NOx and this does not affect it. In general, the by-product produced when urea acts as a reducing agent is referred to as Carbon Dioxide. This technology reduces the emissions of NOx by 70 to 95 %.
