| Abstract: | It was analyzed that the problems of phosphoric acid-washing for primary treatment of pelleting tailgas from production of composite fertilizer,and that the causes of large amount of ammonia in the tailgas when water-washing is used for primary and secondary treatments.A technical scheme of using phosphoric acid-washing for secondary treatment is also proposed,whose operations show that the reform is successful and using phosphoric acid-washing for secondary treatment is feasible. |
| Keywords: | pelleting tailgas ammonia phosphoric acid and reform |
