Can a sulfur-based acid production plant produce liquid sulfur dioxide?
Thread Content
The prospects for sulfuric acid are not good; can sulfur-based acid production plants produce liquid sulfur dioxide? Currently, the price of sulfur dioxide can reach around 1500, and it can also be used to produce products such as insurance powder and thionyl chloride. Is it economically viable to carry out this technical upgrade? Please ask an expert for some advice, thank you!
1 Liquid SO2 by sodium citrate method: SO2 is drawn out from in front of the converter; after cooling, it is absorbed using a sodium citrate solution. Subsequently, it is heated to desorb high-concentration SO2, dried with H2SO4, and then compressed to produce liquid SO2. 2 The liquid SO2 produced by the sodium citrate method, when operated efficiently, has a lower cost compared to that of liquid SO2 produced by the pure oxygen method.
The production of liquid SO2 using the sodium citrate method requires high-performance compressors, and the treatment of exhaust gases is also costly； The price of SO2 can’t be that low; it’s probably around 3,000 or so
Upstairs, where can SO2 be sold for 3000? In the past two years, our pure oxygen method seems to have never exceeded 2000.
The compressor has low requirements; it has been in use for several years with no problems at all. There is very little exhaust gas, which is drawn into the acid production system via negative pressure.
Which factory are you from? Our compressors have a high failure rate; we need to learn from this*
The compressors here also break down frequently, with severe corrosion. Do you have any good methods to recommend?
The exhaust gas problem can be easily solved by introducing it into a sulfuric acid system. However, will this have an impact on the catalysts and the overall system? We discharge the gas after absorbing it with liquid alkali, which results in a strong odor of sulfur dioxide in the surrounding area, affecting environmental conditions
For sulfur-based acid production, the SO2 exhaust gas is drawn in under negative pressure at the air inlet in front of the drying tower; for pyrite-based acid production, the SO2 exhaust gas is drawn in under negative pressure in front of the electrostatic precipitator, and this does not have any impact on the system.
“Can a sulfur-based acid production plant produce liquid sulfur dioxide? ”Of course. Low equipment investment and simple operation. That’s how our factory operates.
I can’t say much; if I reveal any more, the boss will hold me accountable :P
