본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (7)

  1. 제1단계에서 질소 산화물을 함유하는 가스를 탄산암모늄 및/또는 중탄산암모늄 용액에 흡수시켜 아질산 암모늄 용액을 형성시키고, 제2단계에서 이산화탄소를 함유하는 생성된 폐기가스를 암모니아성 수용액에 흡수시켜 탄산암모늄 및/또는 중탄산암모늄을 형성시키고, 이어서 이러한 형태로 제1흡수단계로 반송시킴으로써 아질산암모늄의 제조시의 폐기가스로부터 NO를 완전히 회수하는 방법에 있어서, 이산화탄소를 제2흡수단계에 도입시키기 전에 이산화탄소를 함유하는 폐기가스를 0.1 내지 5중량%의 질산을 함유하는 중간 농도의 황산과 접촉시킴을 특징으로 하는 방법.
  2. 제1항에 있어서, 중간 농도의 황산이 0.2 내지 1.5 중량%의 질산을 함유하는 방법.
  3. 제1항에 있어서, 중간 농도의 황산의 농도가 30 내지 70중량%인 방법.
  4. 제1항에 있어서, 중간 농도의 황산의 온도가 25 내지 80℃인 방법.
  5. 제1항에 있어서, 황산의 농도를 물 및/또는 묽은 질산용액을 첨가하여 조절하는 방법.
  6. 제1항에 있어서, 중간 농도의 황산의 농도가 55 내지 65중량%인 방법.
  7. 제1항에 있어서, 중간 농도의 황산의 온도가 50 내지 65℃인 방법.
