Dry hydrogen sulfide removal from blast furnace gas
Thread Content
Is there any use in China of high-temperature decomposition of sodium bicarbonate to produce porous sodium carbonate for dry hydrogen sulfide removal, in the field of desulfurization of blast furnace gas? In other words, at 100°C in the solid state, can sodium carbonate react with gaseous hydrogen sulfide?
I have seen them use slaked lime to make a slurry for desulfurization
Could you please provide the specific manufacturer? I’d like to learn more about it. Thank you very much!
First, it is necessary to determine whether the form of sulfur present in blast furnace gas is hydrogen sulfide or sulfur dioxide. Currently, the soda ash dry desulfurization method is mainly used for removing sulfur dioxide, hydrogen chloride, hydrogen fluoride, etc.; since hydrogen sulfide has lower acidity, the efficiency of this method is somewhat lower. Additionally, the gas temperature is generally above 140 degrees Celsius. I am currently engaged in dry desulfurization and dust removal. For more details, please contact me: QQ: 9213968
