Selective Catalytic Reduction (SCR): A Proven Solution
Selective Catalytic Reduction (SCR) is an effective and cost-efficient method for reducing nitrogen oxides (NOx) in industrial exhaust gases, particularly in low to medium temperature environments. NOx, primarily made up of nitric oxide (NO) and nitrogen dioxide (NO₂), is a major contributor to environmental issues such as air pollution, smog, and acid rain formation.
Industries such as power generation and petrochemical processing are significant sources of NOx emissions, primarily originating from equipment like coal-powered boilers, combined heat and power (CHP) plants, industrial furnaces, reformers, and cracking units. Nippon Shokubai’s advanced De-NOx catalysts are tailored to optimize the performance of SCR technology, providing substantial NOx reduction and ensuring compliance with rigorous environmental regulations.
