[1] [2] If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part
The isocyanic acid reacts with the water vapor and hydrolyses to carbon dioxide and ammonia: HNCO + H 2 O → CO 2 + NH 3. Overall, thus far: (NH 2) 2 CO + H 2 O → 2 NH 3 + CO 2. Ammonia, in the presence of oxygen and a catalyst, reduces two different nitrogen oxides: [14] 4 NO + 4 NH 3 + O 2 → 4 N 2 + 6 H 2 O ("standard SCR") and 6 NO 2 ...
