4.3.1.1 Flue-gas from the primary reformer<br />
The flue-gas volume, at 3% (dry gas base) oxygen, for a gas-based conventional steam<br />
reforming plant producing 1,500t.d -1 , is approximately 200,000Nm 3 .h -1 , containing about 8%<br />
CO 2 (dry gas base), corresponding to 500kg CO 2 .t -1 NH 3 . The flue-gas volume from excess<br />
air reforming may be lower. The other pollutants in the flue-gas are:-<br />
NO x : 200-400mg.Nm -3 , (98-195ppmv), or 0.6-1.3kg.t -1 NH 3 expressed as NO 2<br />
SO 2 : 0.1-2mg.Nm -3 , (
