This is a flue gas cleaning process in which an aqueous urea solution is mixed with the flue gas and this mixture is fed through a reactor with a catalyst.
The exhaust gas, into which an aqueous ammonia solution is dosed in a controlled manner using SCR technology, is fed into the catalyst where the final chemical reaction takes place. The catalytic reduction produces molecular nitrogen (N2) and water vapour (H2O). These products are harmless and form a natural part of the Earth’s atmosphere.
