Sodium pyrosulfite is produced from pyrite; what methods are used to address the drying of SO2 exhaust gases?
Thread Content
In the process of producing sodium metabisulfite from pyrite, what method should be used to dry the SO2 exhaust gas before it can be fed into fans for the production of sodium metabisulfite? Is there anyone expert who can help?
Don’t you use 93% acid for drying at home?
The market for sulfuric acid is poor at the moment, and we want to switch to producing other products; therefore, it’s no longer possible to use sulfuric acid for drying.
The cost of producing pyrosulfide after drying sulfur dioxide is too high.
Yes, if there’s a way to use wet flue gas, that would work.
Replace the sulfur dioxide fan with one made of special stainless steel material; (there are no issues behind the electric fogger)
Are there any actual use cases?
What is the pressure in the sulfur dioxide exhaust pipe? At a pressure of ≥0.09 MPa, sodium pyrosulfite or anhydrous sodium sulfite can be produced directly. 20 years of expertise in the production of pyroglucoses! 15762500263
Owner, we specialize in the production of sodium metabisulfite centrifuges; we would be happy to work together if there’s a chance
Dear poster, may I ask which manufacturer’s drying device with concentrated sulfuric acid is used in your household? I can’t find suppliers for this type of product
