| Abstract: | Six existing heat exchangers with double segmental baffles were replaced by four shell-and-tube heat exchangers with ring supporters in retrofitting of conversion section of 20 kt/a smelter off-gas sulphuric acid plant. Compared with the former ones, the latter heat exchanger had advantages of high heat transfer efficiency, small space requirement, low pressure drop, less operation cost and long service life. After retrofitting, the conversion section attained heat equilibrium and electric consumption per tone of sulphuric acid was decreased from 210. 03 kWh to 165. 73 kWh. |
