New process technology for treating ammonia-containing exhaust gases

Thread Content

In chemical production, ammonia emissions are a common issue; processes such as catalyst manufacturing, ammonia synthesis, and the chlor-alkali industry all involve residual or volatile ammonia, which leads to the formation of exhaust gases that pollute the environment. In the past, methods such as absorption to produce ammonia water, acid treatment to produce sulfuric acid, and thermal combustion were used for handling this problem, but these approaches inevitably caused secondary pollution, and their effectiveness in dealing with ammonia was not satisfactory. Ammonia is a malodorous substance, and strict control over it remains a challenge for factories. After years of research and development, a new catalytic decomposition process has been developed for use in the chemical industry. With the help of specially designed catalysts, ammonia can react with oxygen in the air at relatively low temperatures to produce nitrogen and water, thus opening up a new approach to ammonia treatment. This method has been successfully applied in areas such as catalyst production, hydrogen cyanide production, and the chlor-alkali industry.
