Does China have advanced conversion and heating methods for producing sulfuric acid?
Thread Content
I just read a paper: the general idea is that under normal operation in Phase 2, if Phase 1 is shut down for maintenance and heating is applied, appropriate sulfur dioxide temperatures can be introduced at the inlet and outlet of Phase 2’s boiler to raise the temperature in Phase 1’s conversion unit; thereafter, Phase 2 can resume normal operation using the gas from the second absorption tower. Do the experts think there are any difficulties with this approach? Does China have such an advanced heating method for converting sulfur into sulfuric acid? Are there any manufacturers using it?
Doesn’t the sulfur incinerator need to be heated?
This isn’t really considered an advanced method of heating either.
The shaft of the sulfur dioxide fan vibrates severely
Keep SO2 under control. The reaction heat, together with the electrical heating from the electric furnace, helps to increase the temperature, thereby reducing the time required for the converter to reach the desired temperature
Have any manufacturers used it?
I believe advanced heating can be cyclic heating, and internal circulation heating for conversion can be considered the method with the lowest energy consumption.
Preheat the converter using a sulfur incineration furnace for indirect heating (with dry air)
