How to produce ammonium sulfide from 3% H2S gas
Thread Content
How can acidic gas with a 3% H2S content from low-temperature methanol washing be used to produce ammonium sulfate? Additionally, if a furnace is used to first convert substances into SO2 and then sulfur ammonium is produced, should the acidic gases be fed into this furnace through the burners, or should two feed inlets in an annular shape be created on the furnace chamber, as in the exhaust gas furnace used by Ho Feng? Which approach is better? Why? Looking forward to a reply, thank you!
Completely burning H2S gas to sulfur dioxide, and then using the ammonia desulfurization technique, can yield sulfuric acid
I agree with the approach suggested in floor 2~ The sulfur content is too low to be suitable for the current popular sulfur recovery processes~ It’s necessary to completely burn the H2S gas into sulfur dioxide, and then using the ammonia-based desulfurization technique, sulfuric acid can be produced. By learning more about this ammonia-based desulfurization technique, one can figure out how to proceed with the process
If there are no other impurities in the exhaust gas, it is possible to send this gas to the outlet of the absorption tower in the exhaust gas treatment unit of the sulfur recovery system, where it can be mixed with the purified exhaust gas before being sent for solvent regeneration.
Due to the low gas volume, using the ammonia desulfurization method is also not very economical； The project does not have any other sulfur recovery facilities, and the composition of the coal limits its sulfur content ； I’ve considered burning it after concentrating it; that way there would be less gas volume, which might make it easier to burn. Does anyone know how to calculate the parameters of the furnace? Such as dimensions, outlet gas composition, and so on.
3% concentration? ? Why doesn’t the poster use a sulfur recovery process? A process similar to clinsulf?
Owners should not produce sulfur; the output is too low and the investment required is too high
Following the original poster’s approach: acid gas, air, and fuel gas burn in the combustion furnace; the combustion exhaust gases undergo ammonia absorption, oxidation, crystallization, drying, and packaging. Another approach: catalytic oxidation for sulfur recovery.
