A novel process for removal of nitrogen oxides (NOx) from flue gases
with iron filings reduction following complex absorption in
iron-ethylenediaminetetraacetic acid aqueous solution is proposed. The
reaction mechanism involved in the process is discussed briefly. The
parameters influencing the process, including the concentration of
ferrous chelates, initial pH, amount of iron filings, temperature, flow
rate of the flue gas, and inlet nitric oxide concentration and oxygen
content of the flue gas, are researched in detail. The optimal NOx
removal conditions are established. The regeneration and circular
utilization of the absorption solution also is studied.
