- | Nitrogen oxides essentially arise from the nitrogen content of the fuels in combustion processes and at temperatures above 1,000 ° C also from air nitrogen. Another source of NO,,x,, is the electrolysis in primary aluminium production due to the presence of nitrogen in the anode, which can be oxidized to NO,,x,,. All these emission sources resulting from energy related processes | + | No improvements |
- | Therefore, all NO,,x,, emissions will be reported there. If other sources of NO,,x,, have quantitative effects is not known. The inventory compiler will try to get reliable information from the relevant industry association. | + | ===== Bibliography ===== |
