A method for producing a nitrile compound, including: a first step of introducing, into a reaction vessel, a cyclic compound having an organic substituent, ammonia and a raw material gas containing air, and reacting the raw material gas in the presence of a catalyst to produce a nitrile compound; a second step of exhausting the reaction gas from the reaction vessel and separating the nitrile compound from the reaction gas; and a third step of collecting a mist from a first residual gas obtained by separation of the nitrile compound from the reaction gas, and removing the water and ammonium carbonate in the first residual gas. |
