This paper provides an in-depth examination of various methods for treating nitrogen oxides (NOX) in nitric acid exhaust gases, a significant environmental concern in industrial pollution management. The study analyses several techniques, including Selective Catalytic Reduction (SCR), Non-Selective Catalytic Reduction (NSCR), water absorption, dilute nitric acid absorption, alkaline solution absorption, extended absorption method, and adsorption methods (both conventional and pressure swing adsorption). Each method's principle, efficiency, and practical challenges are discussed, highlighting their advantages and limitations. The paper aims to offer insights into the selection of appropriate NOx treatment technologies based on specific industrial needs, environmental impact, and economic considerations, contributing to the development of more sustainable Industrial practices.
