| Abstract: |
| Transformation scheme of 1 200 kt/a copper smelting flue gas acid production system in Zijin Copper Co., Ltd. was described including flue gas purification, transformation, absorption, and tail gas desulfurization. The operation practice shows that automation degree of the system has been improved and the conversion rate is 99.9%. The exhaust gas emission drops from 230 mg/m3 to 43 mg/m3 on average. The effect of energy saving and consumption reduction is remarkable, and the operation is stable and economical. |
