How to remove activated carbon dust generated during desulfurization, denitration, and gas stripping?
Thread Content
In the activated carbon desulfurization and denitration process, the SO2-rich gas coming out of the stripping tower contains a large amount of activated carbon dust. This gas enters an ammonia wash tower, where it results in a dilute sulfuric acid solution; but how can the impurities caused by the activated carbon dust be removed? Remove before washing or remove after washing. I’d like to ask everyone for any good methods
The activated carbon is regenerated at 400°C; the temperature of the gas exiting the system is around 400°C. Can a bag filter be used in this case?
It can’t be used at such high temperatures :)
