Waste gas containing nitrogen oxide (NOx), under the conditions of reductors (urea, ammonia or liquid ammonia), and through selective catalytic reduction (SCR) catalysts, is converted into non-toxic and harmless nitrogen gas (N2) and water (H2O).

We combine this technology with other technologies, which are widely used in electric power, chemical industry, ships, glass, steel, internal combustion engines, gas turbine and garbage incineration installation, biomass boiler, and many other areas, providing tailor-made solutions for pollution control.
