How are nitrogen-containing compounds purified during coal gasification?
Thread Content
What impact do nitrogen-containing compounds such as HCN, NH3, and NO produced during gasification have on the system? How can one achieve purification?
I hope all fellow sailors will actively share their opinions!
No special measures are required; after gas generation, it can be absorbed by water if water quenching is used. If used after the waste boiler, it can be absorbed during the pretreatment stage prior to entering the low-temperature methanol washing process ； In wet flue gas desulfurization, it can also be absorbed by an aqueous solution.
Are nitrogen oxides highly soluble in water? And because of its low content, it gets absorbed when in contact with an aqueous solution? Thank you for your advice!
HCN is generally converted to NH3 through conversion; NH3 is removed by installing an ammonia scrubber at the exit of the conversion unit or at the inlet of the methanol wash unit.
It seems that the transformation pair also has a significant effect on gas conversion.
HCN and NH3 can be removed separately, so at which stage can NOx be removed?
Could you provide specific details on the knowledge related to primary cooling and electrostatic capture operations?
Could you explain the electric capture operation you mentioned? Thank you!
