Where have you taken the exhaust gas from coking desulfurization?

We designed to direct the flue gas resulting from desulfurization to the upper part of the heating furnace’s chimney; later, the burners were modified, but the results were not satisfactory. Subsequently, the environmental protection agency installed an online monitoring system, and it was found that the sulfur dioxide levels in the flue gas exceeded the allowed limits. Even after further modifications to the chimney, those limits were still not met. Could anyone suggest a suitable place for this flue gas to be directed?
Can be produced: 1. Sulfuric acid 2. Sulfur 3. Sodium hydrosulfide 4. Sodium thiosulfate 5. Thiourea
Either the desulfurization unit or the sulfur unit will do; in either case, the only option left is to use a flare
Since the desulfurization alcohol off-gases contain oxygen, sulfur deposition may occur at the inlet of the flare gas tank compressor in the presence of oxygen, which can affect the operation of the compressor. Removing sulfur might lead to excessive SO2 levels in the sulfur-containing off-gases; it is recommended to route these gases to catalytic combustion
The exhaust gas contains some unreacted oxygen; isn’t this unsafe for a low-wattage system?
Is the liquefied gas in your facility desulfurized on-site, and can it meet the required standards? We are now proceeding to the liquefied gas desulfurization unit, which is part of the catalytic system, for in-depth desulfurization treatment
