For the production of acid from copper smelting flue gas using Pierce-Smith converters (referred to as PS converters), since these converters achieve rapid desulfurization during the second cycle (copper production phase), resulting in high SO2 concentrations, the flue gas treatment capacity required for acid production must be capable of handling such peak levels (when both the smelting furnace and the PS converter are in operation at the same time). In fact, during the second cycle of the PS converter, the curve of SO2 concentration in the converter flue gas versus time is not flat; rather, it has a peak. This peak is very important for determining the flue gas treatment capacity of the acid production system designed to handle the flue gas from this process. No literature has reported the aforementioned curves to date; therefore, determining the peak conditions of copper smelting flue gas with PS converters relies on experience. With Jiangxi Copper Guiyang adopting chromatographic thermometers, SO2 concentration meters, and O2 concentration meters to determine the end point of PS converter blowing, it has become technically possible to plot the desulfurization curves for two cycles in PS converters; let’s look forward to this moment together^_^
For phase B, it is 1.4 times the value provided by the metallurgy specialty; for phase S, it is 1.33 times that value. This represents the maximum amount of pure sulfur that can be produced per converter; Multiple converters can simply perform time fitting based on their own operation cycles.
It seems that, given the current trends in development, converters are likely to be replaced; Energy conservation and environmental protection in the smelting process ; Considering the acid production operating costs, continuous blowing is more advantageous
Continuous blowing is also a clear drawback, as it fails to achieve sufficient refining intensity. The PS converter can increase the blowing intensity by adding cooling material.

This value is similar for small converters, while the peak effect is less pronounced for large converters.
