What to do if the absorption device for producing acid from low-concentration flue gas gets clogged easily?
Thread Content
Dear friends, our company has observed that the acid production equipment tends to get clogged during the process of converting smelting exhaust gases into acid. After analysis, we suspect that high levels of hydrogen sulfide may be responsible for this issue, as it causes sulfur dioxide in the flue gas to be reduced to elemental sulfur during the subsequent acid production reaction, thereby leading to clogging. We would appreciate it if you could help analyze this situation. Thank you in advance (Ours is acid production using flue gas with low concentrations of sulfur dioxide)
Is it the production of acid from flue gases from lead-zinc smelting? Purification indicators, such as dust, fog, water, arsenic, fluoride? What is the temperature drop in the electrostatic precipitator?
For tin smelting exhaust gas, the Canadian Consol process is used for the equipment.
Is there a smelting furnace? Analyze the hydrogen sulfide content in the flue gas from the carbonization furnace.
It is likely that insufficient acid concentration is causing corrosion of the equipment and pulverization of the catalyst; it is advisable to use an ion liquid exhaust treatment system to divert a portion of the flue gas, thereby stabilizing the operation of the sulfuric acid process, which will yield better results
There is a smelting furnace, and the hydrogen sulfide gas level has been monitored; it’s around 2,000 milligrams per cubic meter.
I would like to ask that there are currently two methods for enriching low-concentration SO2 on the market: one is treatment with ionic liquids, and the other is treatment with regenerated amines. What are the differences between them? How to choose
The ion liquid technology is mature; get in touch more often
