Removal of organic gases
Thread Content
Friends, are there any of you who did well in chemistry courses? I have a question: For activated carbon produced via the slurry method at around 800°C, when carbon regeneration is carried out using a thermal regeneration furnace, the exhaust gas still has a strong unpleasant odor even after being treated through three stages of adsorption using acid, alkali, and carbon. Our preliminary analysis suggests that this odor is caused by organic substances such as methane, which are produced by the high-temperature decomposition of flotation reagents like xanthate and No. 2 oil; these substances cannot be absorbed by acids or alkalis. So, may I ask: what organic solvent can be used as an absorbent to absorb these organic gases? Or what equipment can be used to remove them through combustion?
Let’s light a torch and burn it; methane, when burned, turns into water, which is completely harmless.
A catalytic combustion tower enables the flameless combustion of organic waste gases at lower ignition temperatures. It is recommended to burn first, followed by acid and alkali cleaning
Hydroxyl deep oxidation is used to oxidize it into water and carbon dioxide; please contact me for details.
Regenerative oxidation combustion, in alkaline washing, under dual oxidation treatment with ozone and hydrogen peroxide
With the temperature already so high, it’s easy to ignite it no matter how
