<p>A postcombustion gas containing NOx emissions is passed through a bed of fecal material (27) adapted to convert NOx to NO3 to remove the NOx from the gas and raise the nitrate level in the fecal material (27) and thereby produce a fertilizer which is rich in nitrogen. The gas is then passed through a carbon filter (44) to remove volatile organic compounds and condensed to remove water of combustion.</p> |
