Description
ムンド/ヴェーバー著、刊行物"無機物の窒素結合"、カール・ハンザー出版、ミュンヘン ヴィーン 1982 "ヴィンアッカー/キュヒラー著、化学技術第二巻、無機物の技術1〜4版"
・ 残留ガスの膨張が少なくとも二つの段において、エネルギーを回収することにより行われること、および
・ この場合各々二つの膨張段の間に、450℃を超える温度に、予め膨張した残留ガスを加熱するための少なくとも一つの装置が設けられており、この加熱が硝酸の製造プロセスから出る廃熱を利用すること、
により解決される。
が発生する。このNO富ガス6をまず部分蒸発器/過熱器7内で弱冷却し、その後NO富ガス8を残留ガス(下部を見よ)を加熱するための、ガス/ガス熱交換器9および10内で利用し、そして最後に部分蒸発器/エコノマイザー11内でNO富ガスを冷却する。部分蒸発器/エコノマイザー11内において、供給水14から、まず水/蒸気12から成る混合気が生産され、続いてそれから部分蒸発器/過熱器7内において、過熱蒸気13を回収する。冷却されたNOガス15をNO圧縮機構16内で二次圧縮する。二次圧縮されたNOガス17をガス/ガス熱交換器18内で冷却し、かつこのNOガスを吸収機構19内で硝酸20に転換させる。

- 単加圧法あるいは複加圧法による加圧下で、アンモニアと酸素を含むガスから50%〜70%の濃度の硝酸を製造する方法において、
・ 残留ガスの膨張が少なくとも二つの段において、エネルギーを回収することにより行なわれること、および
・ この場合各々二つの膨張段の間に、450℃を超える温度に、予め減圧された残留ガスを加熱するための少なくとも一つの装置が設けられており、この加熱が硝酸の製造プロセスからの廃熱を利用することを特徴とする方法。 - 膨張段のガス入口温度が500℃〜600℃の間であり、残留ガスの膨張時に発生したエネルギーを回収して得られる駆動エネルギーを圧縮段および発電機に供給することを特徴とする請求項1記載の方法。
- 残留ガスの膨張時に発生したエネルギーを回収して得られ、かつ圧縮駆動に必要なエネルギーを差し引いてもなお過剰に余る駆動エネルギーにより、電気エネルギーを発生させるための発電機を駆動することを特徴とする請求項1または2に記載の方法。
- 電動発電機を使用し、この電動発電機が電動発電機の出力に基づいて、圧縮作業を設備の新たな始動時に単独で行うことができることを特徴とする請求項3記載の方法。
