In response to the problem of excessive flow of concentrated acid pump in the drying and absorption section of sulphuric acid system,which poses a safety hazard in the production process,it has been demonstrated and analyzed that the concentrated acid pump has been retrofitted with frequency conversion for energy saving.After the retrofit,759 732 kWh/a of electricity can be saved and 757.4 t/a of carbon dioxide can be reduced,which has significant economic and social benefits.
