Treatment of sulfur recovery exhaust gas
Thread Content
Common methods for treating sulfur recovery exhaust gases involve combustion or ammonia-based desulfurization before emission. Some people now suggest that the exhaust gases should be sent directly to boilers for treatment. I would like to ask everyone about the advantages and disadvantages of these two treatment methods
We burn the exhaust gases, and after desulfurization using the power wave sodium method, the smoke is released through the chimney.
Should it also be sent to the boiler for treatment after being incinerated? Go for flue gas desulfurization.
Sending the flue gas directly from the furnace outlet to catalytic flue gas desulfurization is also an option
Our factory is currently working on this.
The flue gas after combustion can also be desulfurized using seawater.
The exhaust gas from the Claus process does not require hydrogenation; it is burned directly and then desulfurized using ionic liquids, with the resulting SO2 being returned to the Claus process
Some time ago, I came into contact with a domestic design firm; they advised against sending the boiler due to the long distance, fearing corrosion caused by dew points along the way； It is said that an alkaline wash can be added before In rows, to form a sodium sulfate solution which is then sent to the wastewater system or used in gasification coal grinding
Indeed, if it’s a heat pump boiler, the distance is too great
Are there any projects that use this technology?
Yes, this technology is already very mature
